Everyone knows ItWasHisSled, but most of the time, posting a {{Spoiler}} without any warning will get you cursed, flamed, and even banned from any [[{{Fora}} forum]] you decide to post it on.

However, there are some things you just ''don't'' want to spoil, warning or otherwise. With all the incredibly profitable uber-franchises permeating the pop-culture landscape, companies nowadays tend to be incredibly sensitive about plot details of their upcoming books, movies, TV shows, video games, etc. [[ContentLeak getting out to the public before the release date]]. This is especially true on forums where [[UsefulNotes/ForumPeckingOrder The Gods Themselves]] (series creators, staff) tend to frequent, because admins of those forums fear that any such leak might be blamed on said staff member, and so they'll be especially diligent in deleting said spoilers. Companies have been known to have lawyers patrol the popular {{fora}} of the internet, seeking out any possible sign that spoilers of their property have leaked. Basically, the difference between an ordinary spoiler and one of these is that you can get away with posting a regular spoiler if you give sufficient warning, while this concern situations where someone can be punished for revealing a spoiler even if they give all the warning in the world. The simple act of discussing the plot spoiler itself is what's being punished.

If you post spoilers for the latest installment of ''Rise of the Uber-Ultimate Hype Machine Wizards 12'' before 12:01 AM on X Day Of Y Month of Z Year, they won't just scream "[[BigNo Nooooooooo!]] [[MemeticMutation You bitch! YOU BITCH!]]" They'll sue you. ''Hard''. If said spoiled franchise is particularly [[CashCowFranchise lucrative]], they'll send [[TheMafia Mafia]] goons to your house to beat you and your family with reeds.[[note]]Not really, but the effects of the [[Film/Life1999 consequences and repercussions]] will likely amount to that.[[/note]]

And ''then'' [[ScrewedByTheLawyers they'll sue you]]. '''''[[SeriousBusiness Hard]]'''''. [[TitleDrop Spoil At Your Own Risk]].

Expect to see such spoilers running wild around [[TheInternet the Interwebs]] right after said work has been released.

Contrast LateArrivalSpoiler. Compare DoNotSpoilThisEnding, ContentLeak, and StreisandEffect for when this is unsuccessful. See also FoilerFootage, where creators go so far as to create fake or multiple alternative versions of scenes so that insiders won't be able to spoil.

!!Examples:
[[foldercontrol]]

[[folder:Film — Animated]]
* This is probably why material for ''WesternAnimation/FrozenII'' hyped up "Into The Unknown" as the film's SignatureSong, as the film's actual big musical moment for Elsa, "Show Yourself", was much more difficult to describe without spoilers. In fact, merchandise depicting [[spoiler: the dress she wears in the latter scene]] wasn't released until a few months after the film had debuted in theaters.
* Pixar tried to hide Bing Bong from ''WesternAnimation/InsideOut'''s promotional material as he plays a key role in the movie's plot.
* 20th Century Fox put on a big show of being VERY secretive about spoilers for ''WesternAnimation/TheSimpsonsMovie'', up to and including taking steps similar to those taken by Scholastic lawyers to prevent plot details from leaking out before the movie was screened officially for critics and audiences in Springfield, Vermont, the site of the film's premiere.
[[/folder]]

[[folder:Film — Live-Action]]
* Prior to the much-hyped release of ''Film/AvengersInfinityWar'', the Russo brothers posted a letter to fans on social media, asking them not to spoil the film for others and using the hashtag [=#ThanosDemandsYourSilence=]. A video with the film's cast was later released, with the same message and the same hashtag. This didn't stop the film's climax from undergoing MemeticMutation within ''days'' of its release.
** Happens again in ''Film/AvengersEndgame'' with the Russo brothers issued a letter again on social media, telling fans not to spoil the movie after the news of leaked footage from the movie being shared online.
* Tyler Nelson was an extra and trained dancer who was intended to appear in ''Film/IndianaJonesAndTheKingdomOfTheCrystalSkull''. When he blabbed spoilers about the movie, not only did he violate his nondisclosure agreement (and was thus sued), but [[DeletedRole the scenes he was a dancer in were cut from the movie]].
* ''Film/{{Psycho}}'' implored the viewer not to release the shocking secret to friends after seeing the movie. Given that ItWasHisSled, it didn't work, though it was really [[PopCulturalOsmosis inevitable]]. Unless that was his plan all along. In fact, Alfred Hitchcock ''actually ordered movie theaters not to let anyone into the theater once the movie started'' (this was in an era where most movie-goers would show up 30 minutes late, sit through the credits, and then watch the first 30 minutes of the next viewing).
* Many of those who saw ''Film/{{Serenity}}'' at various pre-screenings held across the U.S. were at the forefront of keeping the spoilers (and THE spoiler) under wraps in an odd form of self-policing.
* ''Franchise/StarWars'' examples:
** When ''Film/TheEmpireStrikesBack'' was being filmed, Creator/GeorgeLucas went so far as to ''change the line in the script'', dubbing it over in post-production, so that no one but he, Creator/JamesEarlJones, Creator/MarkHamill (who needed to [[EnforcedMethodActing react properly]]) and a ''very'' select group of the production crew would know [[LukeIAmYourFather Vader's relation to Luke]] before the premiere. Of course, that was then, [[ItWasHisSled and this is now]].
--->"No, Obi-Wan killed your father."
** There was another one related to Darth Vader. Supposedly, the scenes in ''Film/ReturnOfTheJedi'' with Vader outside his mask were shot with Creator/DavidProwse in the makeup, finally getting his face shown onscreen. However, when being interviewed on a late night talk show, he bragged "You'll finally get to see my face!" Cue George Lucas getting very angry, and then re-shooting those scenes with a different actor, pretty much just to get back at Prowse for spoiling that Vader would be helmetless in at least one scene.
*** It's clear that David Prowse was horrible at keeping secrets, as he discussed a spoiler about Vader's relationship to Luke when he was interviewed by a small California newspaper.
** Something similar happened when ''Film/AttackOfTheClones'' was in pre-production. [[WhatCouldHaveBeen Lucas offered the role of teenage Anakin to Leonardo DiCaprio]], who gave it away in an interview. As a result he was kicked out and Hayden Christensen got the role instead.
* After the mass leaks of character design sheets, script drafts, and more from the first live-action ''Film/{{Transformers|2007}}'' movie, some die-hard fans went as far as to hack Michael Bay's computer during filming of ''Revenge of the Fallen''. Bay then went out of his way to announce that those working on the movie would be intentionally releasing misinformation as "leaks" to throw out red herrings for the fanbase. Of course, some speculated that the misinformation campaign itself was an attempt to cast doubt upon said leaks.
* There was much hype over preserving the secrecy of the plot of ''Film/TheXFilesFightTheFuture'' film. Including: printing the scripts on red paper with red ink so they couldn't be photocopied, only giving supporting actors the parts they needed for their scenes, each script being numbered and signed for, etc. etc.
[[/folder]]

[[folder:Literature]]
* Most notably, the Franchise/HarryPotter franchise, particularly for the last two books of the series, ''Literature/HarryPotterAndTheHalfBloodPrince'', and ''Literature/HarryPotterAndTheDeathlyHallows''. The company distributing the books went so far as to make every owner of bookstores that received the books sign non-disclosure agreements subjecting them to heavy fines and lawsuits if they dared speak a single word about the content of the books. Scholastic went so far as to demand that readers who were accidentally sold a copy of the book not read it until the release date, though J.K. Rowling herself soon stepped in to say that those who purchased the books could read them, as long as they not spoil the contents of the book until the official release date. (Although how the prohibition would have been enforced anyway is a mystery.) Even as the editor typed these words, the authorities behind the DMCA were stalking their way through the internet, threatening site owners with legal action if their members post Harry Potter spoilers before the release date. [[RevealingCoverup This may end up backfiring]], as the rush to clamp down after the posting of a few leaks of questionable authenticity raises suspicions about their authenticity not being so questionable after all. But then again, there were ''so many'' fake spoilers going around that it was hard to figure out which of them were legitimate.
* When an early, incomplete draft of the ''[[Literature/TheTwilightSaga Twilight]]'' series novel ''Literature/{{Midnight Sun|2020}}'' was leaked in 2008, the author was so frustrated by the experience that she discontinued work on it and put it on indefinite hold, famously saying that if she completed the book in her current state of mind, she'd have let the villains win.
[[/folder]]

[[folder:Live-Action TV]]
* Played straight and subverted with FOX during ''Series/TwentyFour''[='s=] run. During the third season, a ''24'' spoiler blog revealed plot summaries for upcoming episodes (even ones that hadn't been filmed yet), and spoiled a script that ended with Ryan Chappelle (the former division director of CTU in the second and third seasons) faking his death and going into hiding after a demand by Stephen Saunders. FOX understandably went loco over this, tried to shut down the blog (it didn't work) and changed the script so that Chappelle was [[AnyoneCanDie killed off for real]]. In later seasons, however, fans posting on the show's official forums were able to ''walk onto the set of the production and take shooting scripts at will'', leading to fans finding about plot threads that wouldn't be revealed for several episodes. Fox was apparently okay with this, as they never bothered to moderate or police their own board.
* Comedy Central's ''Series/BattleBots'' was filmed in front of a live studio audience, several months before the fights actually aired on television. Rumors abound of event staff actually going so far as to make each and every audience member sign non-disclosure agreements before attending the event, and administrators of ''[=BattleBots=]'' fan forums frequently deleted such spoilers if they were posted, with or without warnings. This is likely because all of the major fan forums were run by/heavily populated by ''[=BattleBots=]'' contestants, who thus had more of a vested interest in keeping the results of the competition close to their chest.
** This did not deter Chuck Pitzer, however, captain of Team Raptor and who entered Ghost Raptor into the 2020 competition. He not-so-subtly hinted on Twitter that the winner of the whole competition would be [[spoiler:End Game]], thus revealing it [[LoopholeAbuse without actually violating his NDA]]. People hoped [[TrollingCreator he was joking and messing with the fans]], but when the episode aired and he was right, he immediately became a pariah among fans and fellow competitors alike, and now [[OvershadowedByControversy he is more known for spoiling the outcome than anything else he's done in his 15+ years in robot combat]]. This event created rumors of its own that Pitzer may have done so intentionally [[SoreLoser out of bitterness from his poor performance that year]].
* ''Series/DoctorWho'':
** [[Recap/DoctorWhoS27E1Rose "Rose"]], the first episode of the new series, was leaked online by an insider a few weeks before it was officially broadcast. The leak was eventually traced back to an employee at the CBC in Canada who was fired over it.
** The BBC sent out the broadcast masters of the 2005 series under a codename in an effort to keep them secret. The selected codename was an anagram of ''Doctor Who'', and ended up being recycled as the title of a spinoff series, ''Series/{{Torchwood}}''.
** Casting is also very secretive. Karen Gillan was hired to act in an upcoming production called "Panic Moon". As it so happens, "Panic Moon" is an anagram for "Companion".
*** ...said revelation (by Karen Gillan, in an interview) lead to Creator/StevenMoffat remarking in another interview that now they needed to find another way to hide future auditions. How much he was really put out by it is anyone's guess. Jenna Coleman later revealed that the code name title used for her audition was "Men on Waves", an anagram for "Woman Seven" (since she was to debut during Series 7).
** Amazon UK screwed up with the release dates and dispatched DVD/Blu-Ray copies of the second half of series 7 to pre-order customers before the final episode had been shown on TV. As a result, Moffat said he would release some footage of Matt Smith and David Tennant together on the set of the 50th Anniversary if no spoilers were revealed. For once, [[https://www.youtube.com/watch?v=2Em8lmmTNkA the fans behaved]].
** Possibly due to fans playing ball with the above, at the San Diego Comic Con in July 2013, Moffat showed the first trailer for the upcoming [[Recap/DoctorWho50thASTheDayOfTheDoctor 50th anniversary special]], but preceded it by warning convention-goers that if video of it leaked onto the Net, there would be no further exclusives at future Comic Cons. Despite the fact that ''months'' passed before an official trailer was released to the public, no video of the Comic Con presentation was widely leaked. The trailer to the docudrama ''Film/AnAdventureInSpaceAndTime'', which was also shown, did turn up, but it's unclear whether Moffat's edict/threat was specifically related to the 50th anniversary trailer alone.
** Both Russell T Davies and Steven Moffat protected spoilers by issuing fake script pages and editing pre-broadcast versions of episodes:
*** To protect the surprise of Rose Tyler's cameo at the end of the Series 4 premiere, [[Recap/DoctorWhoS30E1PartnersInCrime "Partners in Crime"]], review copies sent to media omitted Billie Piper's appearance.
*** John Hurt's cameo at the end of [[Recap/DoctorWhoS33E13TheNameOfTheDoctor "The Name of the Doctor"]] was similarly edited out in review copies.
*** The readthrough for [[Recap/DoctorWhoS32E7AGoodManGoesToWar "A Good Man Goes to War"]] featured a fake ending for the episode. Only afterwards did the key cast members find out the real ending, and the crew didn't know about it until the day of filming.
** When a guest star accidentally left a copy of their script for an upcoming episode behind in a taxi, although the script was returned without major spoilage occurring, the episode, originally titled "The Last Cyberman", underwent a name change to the less-specific [[Recap/DoctorWhoS33E12NightmareInSilver "Nightmare in Silver"]].
** On a few occasions, efforts to keep spoilers secret have been stymied from within:
*** Russell T Davies originally planned to have Christopher Eccleston's regeneration into David Tennant at the end of Series 1 be a complete surprise to viewers, but the BBC's own publicity department destroyed this plan by announcing the actor's departure soon after [[Recap/DoctorWhoS27E1Rose "Rose"]] aired.
*** Tom Baker blew the secret of his cameo in the 50th anniversary special during an interview that ran a few days before the special aired. (To be fair to Baker, he may have thought the interview was to run after the broadcast. This is also believed to have been the case with Suranne Jones, who accidentally revealed the true identity of her [[Recap/DoctorWhoS32E4TheDoctorsWife "The Doctor's Wife"]] character Idris in an interview conducted before the episode aired. In that case, however, the media outlet initially ran a censored version of the interview to preserve the surprise.)
* Creator/GeorgeRRMartin is well aware of his age. So much so that fans of ''Series/GameOfThrones'' don't need to worry if the books never get finished, because the Creator/{{HBO}} writers know all of the important plot points from here on out. One can only imagine what kinds of contracts and threats they were subjected to.
** Due to Martin's infamously slow writing pace, the show has, as of season six, passed the events depicted in the books. Although, given how radically Season 5 diverged from the already published material, along with how many major characters were AdaptedOut, it's hard to tell if anything from the last two seasons comes from the books.
** After the debacle of the entire Season 7 plot outline leaked online months before it aired, HBO put a lot of extreme measures just to ensure that nothing from the final season is leaked to the point that no one takes the script outside of the set and that they have to read it in the set.
* ABC was normally supportive of (or at least pretending to be oblivious to) ''Series/{{Lost}}'''s spoiler community until the end of the third season, when a detailed plot description of the finale, including a major gamechanging cliffhanger, was posted online. ABC launched an internal investigation to find who was responsible, and showrunners Damon Lindelof and Carlton Cuse refused to do any interviews or discuss the finale until Comic-Con three months later (and then sparsely afterwards). The investigation presumably failed, as the same individual spoiled the season 4 finale as well.
[[/folder]]

[[folder:Professional Wrestling]]
* ProfessionalWrestling fans are quite the opposite; they have no problems with spoilers from a taped show, as long as said spoilers are clearly marked. The Wrestling/{{WWE}} itself, however, is another story; they seem rather schizophrenic in their treatment of the subject, in some instances ejecting anybody who even brings a notebook to a TV taping, while at other times posting spoilers on their own official site. Their current stance seems to be somewhere in the middle; they'll allow people to take notes, and even to tape the event, but will not allow the use of cellphone cameras or laptop computers (so that, at the very least, the show won't be spoiled until after the taping is over).
** Notably, when Wrestling/CMPunk delivered his incendiary post-show monologue in the summer of 2011 (in which he insulted the company and leveled several disparaging remarks at Vince Mcmahon and John Laurinitis), the taping which it occurred was one of two shows being shot that night (a week before Independence Day; WWE doesn't film on that date). Naturally, fans attending the event saw the entirety of two weeks worth of shows being filmed at once. As such, they also learned that, at the end of the second taping, Punk was rehired by the company. This led to a massive subversion of the trope when said fans leaked the information, and slammed WWE for attempting to play up the illusion that Punk had been fired (with the company "deleting" his official profile on their website and removing his social media presence).
[[/folder]]

[[folder:Tabletop Games]]
* Major spoilers have happened a few times in [[TabletopGame/MagicTheGathering Magic's]] history.
** The first and most famous one was the Time Spiral spoilers in 2006, where [[ImageBoards MTGSalvation's]] Rancored Elf, a prominent spoiler member, received a preview of 4 cards from Time Spiral Block's first set. This happened during Dissension, nearly three whole sets before Time Spiral was due to be released (about 9 months before scheduled spoilers even begin).
** The second was the New Phyrexia spoiler: An entire set revealed nearly two weeks before the official spoilers were off the ground. This was after Wizards of the Coast took painstaking means to conceal if the third set of Scars of Mirrodin would be Mirrodin Pure or New Phyrexia (something the forums had been speculating for 3 months). In both cases, legal action was taken (Rancored Elf was sued and issued a Cease and Desist, and the people responsible for spoiling New Phyrexia's cards were given a very long ban from DCI-sanctioned events).
** And in 2015, after the flagship card of Oath of the Gatewatch was leaked, you can add another. Cue an article on the official website once the official previews began, reminding the ''Magic'' community [[http://magic.wizards.com/en/articles/archive/feature/why-leaks-hurt-2015-12-16 Why Leaks Hurt]].
** A few years after that, the set Ixalan had a major leak where a few sheets (that is cards on a long sheet, yet to be cut) were leaked.
[[/folder]]

[[folder:Theatre]]
* Agatha Christie's play ''Theatre/TheMousetrap'', or ''Three Blind Mice'', has a twist ending that they implore you to keep secret. Most productions of the play even bill themselves as "the longest-running secret in the history of theatre!", or variations to that effect. Most people actually obey, and so do [[Website/TVTropes we.]]
** A joke among theatreland insiders tells of an American couple going to see The Mousetrap, tipping their cabbie poorly, and having "TheButlerDidIt!" yelled at their departing backs. Fear not if you are spoiler-averse: there is no butler character in the Mousetrap.
** This is also why Christie's short story "Three Blind Mice", a prose version of the play with the same solution, has [[NoExportForYou never been published in the UK]].
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/KingdomOfLoathing'':
** At [[WordOfGod Jick's]] request, a certain EasterEgg in a level 10 quest will never, ever appear on the [=KoLwiki=]. Ever. There's a filter in the in-game chat to prevent it being spoiled there, and spoiling it in the forums will get the mods all up on your ass.
** [[http://forums.kingdomofloathing.com/vb/showthread.php?p=3929260#post3929260 "Riff said he'd give anyone who spoiled the end of the bees storyline in the forums a kick in the balls.]] [[{{Pun}} Bee]] warned."
* This hit Creator/BioWare in full force in the months leading up to the release of ''VideoGame/MassEffect3''. An internal demo build of the game (comprising part of the intro mission, and a quest involving the rescue of a Krogan female) was inadvertently posted on Xbox Live then taken down a day later, and was promptly played, filmed, and uploaded to Website/YouTube by hardcore fans. Then, even more incredibly, a group of users on the Russian [=BioWare=] Social Network cracked the internal code of the demo and found design documents that contained most (if not the entirety) of the game's plot, including morality decisions, surprise character appearances, benefits of having [[OldSaveBonus saved games]] from the previous installments and a complete rundown of every squadmate, weapon, power and location visited. [=BioWare=] employees immediately went on the defensive (saying that the documents were from a pre-alpha version of the game), going so far as to send famed internet gaming board [=NeoGAF=] a cease-and-desist letter (courtesy of Microsoft) asking not to reveal the spoilers, and permabanning anyone who made any more than a passing mention of the leaked documents. Then, a few weeks later, the official demo release was once again cracked by fans, who discovered 20 minutes worth of Codex dialogue, the game's loading screens, and dialogue for the [[spoiler:Prothean]] secret character.
* Creator/{{Konami}} understandably didn't want reviewers of ''VideoGame/MetalGearSolid4GunsOfThePatriots'' revealing crucial plot spoilers in reviews before the game was released. They subsequently went as far as to prevent reviewers from "spoiling" the game's excessive mandatory install requirements and the length of its excessive cutscenes.
* Harmonix, the developers of ''VideoGame/RockBand'' and its sequel, were slammed by playtesters who violated their non-disclosure agreements by posting the entire ''Rock Band 2'' setlist they had played (60 songs of the disc's final 84.) Needless to say, they were sued. Some think that this was a factor in Harmonix's decision to reveal the game's entire on-disc setlist at once.
** They went on to parody this trope in the lead-up to the release of ''Rock Band 3'', where they made an announcement that this time, they were absolutely cracking down on any potential source of setlist leaks... while somebody scrolled through the entire list of songs on a screen behind them.
* When ''VideoGame/{{Scribblenauts}}'' was released early due to hundreds of [=GameStops=] breaking the street date on its release, the moderation staff at Website/GameFAQs went on a rampage at the site's Scribblenauts board. Any topic with gameplay discussion or anything that even appeared to be gameplay discussion was very harshly moderated, mainly because most of the posts were from people who had downloaded the ROM. They were warned for "Illegal Activities", even though some people had actually received perfectly legal copies from stores who had accidentally let it out early.
* Although he has no real power to enforce it (other than perhaps through copyright), ZUN has requested that you not post the endings of the ''Franchise/TouhouProject'' games online. However, it is enforced by many fansites, and what happens if you do it is up to whoever has authority on the site.
* Creator/{{Atlus}} came down hard on people posting videos with spoilers on ''VideoGame/Persona5''. Atlus warned let's players and streamers that if they posted content from the game that was beyond the in-game date of July 7th (later changed to November 19th), they would issue a copyright takedown to remove the offending videos and possibly have the channel shut down. This caused a lot of ValuesDissonance within the fan community. While Japanese fans in general are very respectful about keeping spoilers to themselves and get rather angry when they see spoilers floating around, Western fans found the warning condescending. Not only did Atlus basically spoil that ''something'' was going to happen in the game after the specified date, people that were upset by Atlus' actions and the tone of their message would [[StreisandEffect post spoilers out of spite anyway]] and the most common method used was Twitter bots. One of the big sticking points was that Atlus was threatening to use copyright takedowns to enforce this policy - which westerners saw as flagrant abuse of a system that was meant ''strictly'' for reporting stolen content, ''not'' the enforcement of arbitrary rules by large companies. What also baffled fans about the no spoiler policy is how the game was already out in Japan several months before the English release and thus spoilers were already on the internet to begin with.
* Creator/TobyFox, creator of ''VideoGame/{{Undertale}}'' didn't want spoilers floating around so that people could enjoy the game, but he wasn't going to come down on people that did post spoilers. He also requested fans to refrain from posting sprite sheets online for similar reasons until a few months passed by. Unlike other people or companies that would use everything they could to stop a spoiler from spreading, Toby simply asked for spoilers to be kept to a minimum and left it at that.
** In 2018, he released the first chapter of his next game, ''VideoGame/{{Deltarune}}'', as freeware, and similarly requested that players refrain from talking about it online for the first day of its release.
* Somewhat related is the concept of street dates for games. Typically, a video game retailer will receive copies of games several days to a week before the actual release date. Without exception, these games are marked with specific release dates. If the store sells the game before the release date, it ''can'' be traced, and the retailer will be sued for breach of contract. And then, worst of all, the publisher will not allow that retailer to receive their games until ''after'' the release date (at ''best'', at worst, they simply won't ship games to them anymore). National chains, like Gamestop, are not immune to this, and will be sued just like anyone else (and the offending employee will be fired and subject to prosecution all on their lonesome too). This is SeriousBusiness, folks.
* The highly anticipated ''VideoGame/FinalFantasyVIIRemake'' was released in the middle of the COVID-19 pandemic, which caused some regions of the world to get the game before the official release date and others to get it later due to brick-and-mortar stores being shut down. Square Enix's official Twitter account put out a letter asking those who got the game early not to spoil the story for those who hadn't; unfortunately it fell on plenty of deaf ears, as not only did people livestream the game early (and thus got their channels taken down) but some players who were unhappy with the [[BrokenBase rather divisive]] changes to the original game's plot actively spread spoilers in hopes of souring other players on the remake.
* There is an ongoing war regarding leaked information for Franchise/{{Pokemon}} between the creators and the fans. Pokémon fans tend towards SpoilerHound due to the nature of the games rewarding those who plan ahead, so there is enormous demand for people in various positions to acquire or play the game early to leak the games as far in advance as possible, so much so that [[ContentLeak/{{Pokemon}} the franchise has its own Content Leak page]]. As a result people from the inside have been consistently putting up information about main series Pokémon games, sometimes months in advance, leading to frantic and usually unsuccessful damage control from Nintendo, Game Freak, and The Pokémon Company. The playtesters, bloggers, fansite staff, and retail staff lose their jobs and legal action is taken against them, but they don't care, seeing themselves as taking the fall so the rest of the fans can distribute and share the information online. That is, they know full well of the "Risk" part of "Spoil at Your Own Risk" but deem it WorthIt. There is also always another group ready to do it for the following games.
* When the remake of ''VideoGame/LiveALive'' was released, Creator/SquareEnix began rampantly issuing cease and desists and took down any Website/YouTube videos that showed the game's last two chapters to prevent spoiling, despite the fact it's a remake of a nearly thirty-year old game that was a CultClassic at best, and the trailers for the remake [[TrailersAlwaysSpoil already showed numerous scenes from the last two chapters]] (that said, the game does have [[spoiler:an extra TrueFinalBoss that was not in the original]]). All videos showing the game's remade OST were also quickly scoured.
[[/folder]]

[[folder:Web Original]]
* This is pretty much a rule at Website/GameFAQs for almost every game that hasn't hit its release date, due to the site's [[DigitalPiracyIsEvil strict anti-piracy stance]] and unwillingness to give its users the benefit of the doubt under any circumstances (even if a retailer broke the release date schedule).
* This rule is law over at Blog/MarkReadsHarryPotter and Blog/MarkDoesStuff. Mark Oshiro, and many of his readers, are going through various series for the first time -- so telling them plot twists from future episodes/chapters is a pretty good way to get yourself perma-banned instantly.
* The creators of ''WebAnimation/RedVsBlue'' once locked a WildMassGuessing thread because it got an upcoming plot twist exactly right. They unlocked it later (but before the plot twist was revealed). The thread's title? "[[spoiler:Are Tex and Church A.I.s?]]"
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/StevenUniverse'': [[https://www.reddit.com/r/stevenuniverse/comments/4uk4ed/matt_burnett_addresses_the_leakers_directly/ Matt Burnett]] ''[[https://twitter.com/mcburnett/status/757573493789564928 begged]]'' us [[https://www.reddit.com/r/stevenuniverse/comments/4uj8xu/spoiler_hell_is_coming_what_do_we_do/ not to leak spoilers]] of Weeks 3/4 of "Summer of Steven" online until the episodes had aired. Also, Lapis Lazuli's European Portuguese voice actress Vânia "Blubird" Pereira was fired and replaced after leaking the song "That Distant Shore" from the episode "Can't Go Back" on her Instagram story.
[[/folder]]

[[folder:Other]]
* The American auto industry has careened from one extreme of this to another -- they ''invented'' the big-show release and pre-release security, developed it to the lengths of shipping cars in enclosed railroad boxcars and obliging dealers to soap the showroom windows in TheFifties, at which point even people with only a passing interest in cars would make an annual tour of local dealers in November just to see the new models. Now GM in particular tends to show off new models at the Detroit auto show in January with [[{{Vaporware}} sales to begin the following fall]], meaning they have only the old model to offer for ''almost a year''.
* The American Psychological Association has a vast number of databases of visual and auditory stimuli, along with arousal levels for each stimulus. These databases are kept closely guarded to maintain novelty among the general public, who may end up being part of their experiments at some point.
* Franchise/{{LEGO}} has a strict policy concerning the release and pictures of their new products because rival brands like Mega Blocks need less time and could have rival products on their shelves earlier than [=LEGOs=] release. Most of the time pictures of sets for the new year leak around fall/Christmas when retailers get their catalogues and are only fair game after the New York Toy Fair around February and even then movie-related toys sometimes have their own date. This practice was fought by LEGO recently using preliminary pictures of the sets in very early prototype stages where they are basically rainbow colored shapes and figures only have the most basic connection to the final product if any. Surprisingly it is still A-okay to post detailed descriptions and names of products at any time unless they are Shop@Home exclusives. The main goal of this policy seems to be that children only learn about new products when they see them on the shelf or at LEGO.com which is redundant as this group doesn´t know about fansites and only uses the strictly regulated LEGO.com forum anyway.
* When movie studios do test screenings of films, audience members sign an NDA that say, among other things, they could be sued for up to several million dollars should they leak or spoil anything they saw before the film is officially released. The host typically reminds the audience "if you post it somewhere, we will find you", and given the amount of money involved in Hollywood, that's not an idle threat.
