When coming across something you like, it's generally a good idea to download a permanent copy of it. Deletion of videos is a common occurrence mainly fueled by copyright holders and YouTube has probably the most rabid copyright enforcement on the Internet, to the aggravation of users. Indeed, following some links on This Very Wiki may result in seeing a message that the video (or the poster's account) has been deleted for infringing copyright. This has been exploited by "Content ID trolls": people who falsely report a user's video(s) to get them pulled and their accounts banned.
YouTube has held to the standard that they're not liable for user-supplied content, and because they do promptly remove clips when a copyright infringement notice is received, the courts have agreed with them. Viacom's lawsuit for over a billion dollars against YouTube was tossed out because of the DMCA safe-harbor provisions that exempt a website from being liable for infringement caused by content supplied by users as long as it promptly removes it when a copyright holder complains. YouTube, however, has made some changes including obtaining a compulsory licensenote Yes, we do mean "compulsory license." There are three ways to get a license from ASCAP. (1) If you fit one of the general license classes and you're a small licensee, you pay the general set fee; (2) You don't fit the general classes or you're big enough you think you can negotiate a better license on a special-case basis directly with them, you contact ASCAP and negotiate with them; (3) You can't get a negotiated license or don't like the terms, then you use the Antitrust Settlement terms the U.S. Justice Department got from ASCAP back in the 1940s, you file a petition with the U.S. District Court in Manhattan, and a master from the court will make a determination. The third one is the compulsory license that YouTube obtained. from ASCAP which covers all ASCAP-licensed music that appear in any clip posted on YouTube.
Sometimes a video is only allowed to be viewed in certain countries for copyright concerns. The uploader is able to view it just fine however.
The site itself has been banned temporarily by various countries for various reasons. This includes Brazil, Turkey, Germany, Libya, Thailand, Turkmenistan, and Pakistan among others.
China, Iran and North Korea have all blocked the site permanently since 2009, 2012 and 2016 respectively.
Creator Backlash: Jawed Karim was not pleased with Google+'s integration into YouTube, asking why he needed a Google+ account to comment and bemoaning the fact that he wouldn't be able to comment on the site anymore since he didn't want an account.
If you've ever wondered why copyright trolls and false copyright claims are so rampant, look no further than this behind-closed-doors and still-undisclosed deal YouTube struck with Universal Media Group back in 2009. The letter quoted in the article even states that UMG (and judging by the above copyright troll epidemic, presumably every other content creator on the site) has the power to take down a video for reasons other than copyright infringement. Heres an excerpt from it:
"As you know, UMG's rights in this regard are not limited to copyright infringement, as set forth more completely in the March 31, 2009 Video License Agreement for UGC Video Service Providers, including without limitation Paragraphs 1(b) and 1(g) thereof."
In the early years of The New '10s, Google made it mandatory for all YouTubers to get an account with their Google+ social network in an effort to integrate the two services together - a move that many people understandably called "forced". Eventually, Google got the point from all the complaining, removed the Google+ requirement, and even started the process of shutting down the service for good. Unfortunately, around October 2018, that latter point caused a number of services to simply break on YouTube, including a number of important content creator tools. Markipliershows this problem here, where many of the pages simply lead to a 404 Not Found after Loads and Loads of Loading. On the subscriber side, video notifications were simply broken - they'd either come too late, not at all, or get notifications from decade-old videos and/or people they weren't even subscribed to. He and many other big content creators speculate that because Google+ was so deeply integrated into YouTube, it's now problematic to simply erase it from the site, since a number of YouTube features were dependent on it.
Fan Community Nicknames: Users who have an account and upload videos are commonly referred to as "YouTubers" or "Content Creators".
Fan Nickname: "The Adpocalypse" for the mass exodus of advertisers at the beginning of 2017, followed by the remaining advertisers refusing to put their ads on any channel that wasn't deemed "family friendly". Subsequent similar situations that have many advertisers pulling their ads have been referred to by this name.
Keep Circulating the Tapes: Movies and TV shows that otherwise would be completely forgotten or unlikely to ever be re-released to the public will occasionally make it on the site and, barring the uploads getting removed by the rights' holders, become their unofficial new home. However, this was a lot more common in the early days, as it's now become less and less rare for rights' holders to take action unless they have no plans to re-release them on home video or streaming, in which case they're just content with the free publicity or may even be compelled to make an official re-release.
Missing Episode: Any video that's removed for copyright or straight up deleted by the uploader.
A common complaint among creators is that many of the rules changes since 2016 seem to exist solely to please advertisers and bring the site more money, making it harder for smaller channels to get noticed.
This was the reason YouTube Premium and YouTube Originals were created. It was an attempt to drive users into getting a YouTube Premium subscription and make the site more money. The subscriptions haven't done much for them, making less than 1% of the site's revenue.
The site has come under heavy fire from the community for removing videos the instant they receive an infringement claim without investigating whether the video is Fair Use or not. Unfortunately, YouTube, and "Content Service Providers" in general, are required by law to pull without investigation as soon as they receive proper notice, or else they themselves can be sued by the companies too.
Over the years, YouTube has shown more and more favoritism and preference to partner channels, or channels that have a significant amount of subscribers or viewer activity. For example: are you just an average joe posting videos of things you find interesting or amusing? Well, good luck generating traffic on your videos, because they won't even show up in the search results, regardless of what tags/keywords you put on them. Want to access certain features and perks? You'll need a ton of subscribers and a lot of people watching your videos all the time, otherwise, those features will be locked. In other words, if you're not a partner channel or a regular channel that generates a lot of activity, good luck trying to get any kind of notice, because YouTube has pretty much swept you under the rug.
For channels that are partnered, YouTube made changes to their ContentID copyright identification system in late 2013, making it more difficult to monetize videos. As ContentID was already considered "judge, jury & executioner" by critics before the change, this led to some partners threatening to move to other video sharing sites.
In addition to the Adpocalypse, YouTube's stricter enforcement of their acceptable content policies since 2017 has made it much harder for creators to get their videos monetized on the site.
What Could Have Been: The site was originally a video version of a website called Hot or Not, where users uploaded pictures of themselves and other users would decide whether or not the user is hot or not. However, the creators found this too limited, and later made it a general video site.
The founders reportedly said in several interviews that they sold the website off because of hordes of teenagers (the aforementioned users) uploading copyrighted material on it instead of making their own videos and ignoring its rules, thus destroying their dream for a youtube.
Many of the rule changes concerning what can and can't be uploaded on the site have come into place because of users actively pushing things too far. One notable example was when Bird Box challenge videos began rising in prominence in 2019, leading to YouTube banning dangerous pranks and challenge videos from the site.
