The feeling is pretty much universal among fanfic writers who keep it up for any period of time. It's not unheard of for the latest update of a LongRunner to casually mention that the author now finds the opening chapters to be complete crap, and many a DeadFic only remains dead because the author can't stand looking at it anymore. But here are some specific examples...

* Linkara of Website/ThatGuyWithTheGlasses and WebVideo/AtopTheFourthWall had written "Web of Dimensions" A SelfInsertFic crossing Franchise/{{Pokemon}}[=/=]Franchise/{{Digimon}}[=/=]Anime/SailorMoon under the name [=PsyWeedle=]. It appears to have been taken down, as that one is not on his list of fanfics. Bennett the Sage, however, did manage to get his hands on it for Masterpiece Fanfic Theater. Linkara is there, [[LampshadeHanging tied up and trying to stop Sage.]]
** [[http://www.fanfiction.net/s/101250/1/Web_of_Dimensions Turns out it was actually moved.]]
* Prolific ''[[Disney/TheLionKing Lion King]]'' fanfic author, [=ThatPersonYouMightKnow=], first wrote a series based on ''WesternAnimation/AlphaAndOmega''. Out of shame for their poor quality, he deleted them forever.
* WebVideo/TheFanFictionCritic mans up and reviews her own OldShame in a VerySpecialEpisode. It's... actually not as terrible as she thought. Still pretty bad, but not ''terrible.''
* Notorious furry Sage Freehaven. As a teenager -- and prior to entering the FurryFandom -- he wrote several awful ''WesternAnimation/ChipNDaleRescueRangers'' fanfics called "The Dark Savior Saga", which saw various revisions over his tenure in the fandom and contained innumerable examples of bad fanfic tropes; he also made the mistake of writing them under his real name, only later changing them to bear his FurryFandom pen name. Years later, he had the entire series -- and anything else associated with both that name and his real name, including a [=MiSTing=] of the first fanfic in the series -- stricken from the Rescue Rangers fandom's fan works repository. The only place you can read any of it now is at ''[[http://svamcentral.org/ewic/ Everything What Is Crap]]'', where the [=MiSTing=] of the first story in the series (found under the "American Works" section) remains intact.
* [=GeminiStar01=] has been hovering around FanFictionDotNet for six years now, starting with the second season of ''Digimon'' and ''YuYuHakusho'' fics. Don't bring them up when talking to her, unless it's in person and you want to see the funny color she turns.
* EyrieProductionsUnlimited's first project was ''UndocumentedFeatures'', a work they are still continuing 20 years after it started. However, their second was the {{spinoff}} ''(Gryphon and Zoner get) Hopelessly Lost'', something that the original authors would prefer to have you forget (and which they are, in fact, recreating as ''Bubblegum Crisis: The Iron Age'', a markedly superior work). Also, within the ''UndocumentedFeatures'' body of work, the authors aren't too fond of the initial stories, which had started as a silly blend of wish fulfillment and in-jokes; Gryphon has referred to them as his "crap period."
* Author razzamatazz73 actually ''changed her penname'' because she was so embarrassed by her old fanfics. She even mentions on her [[http://www.fanfiction.net/u/699942/ profile]] that her general rule of thumb is to ignore just about everything published before 2007. Her newer material is noticeably better, considering her rather cliched first fics and more recent ''Film/StarTrek'' and ''FusionFall'' successes. Her review responses to her older stories are particularly amusing, as she usually begins all responses by apologizing to the reader.
* The "[[Fanfic/BothSyllables Both Syllables]]" series ended unfinished (and was then [[OrwellianEditor erased from the Internet]]) for this reason. The author eventually released [[http://630kila.deviantart.com/journal/35059840/ her list of reasons]] for hating the series.
* Andrew Dickman created a short flash animation called ''[[http://www.newgrounds.com/portal/view/76478 Rockman Neo]]''. He intended to create a DarkerAndEdgier fanfic and fan game based on the VideoGame/MegaMan series. However, after some time, Dickman abandoned the project. Not only that, but he started becoming outright hostile to fans who asked whatever happened to ''Rockman Neo''.
* Monica Gilbey-Bieber has a commentary of his old TrollFic, ''[[FanFic/OneLessLonelyGurl One Less Lonely Gurl]]'', [[http://trollseyeview.blogspot.com here]].
* The first multi-chaptered installment of the ''Fanfic/ForGood'' 'verse underwent a drastic rewrite as well as a change of titles, from ''Watermark'' to ''[[MeaningfulName Breakaway]]''. The author cites bad writing, among other things, and is embarrassed in general at the [[WesternAnimation/BuzzLightyearOfStarCommand BLoSC]] fics she wrote when she first entered that particular fandom.
* There was once a Sonic babyfic by Aerogreymon8.0, titled Eggman's New Invention, about Eggman inventing a weapon that turns male people into babies and the female characters having to take care of them. It got taken down somewhere between November 2005 and early in '06. When contacted (that is, while he even went by the aforementioned penname; unknown whether he changed his name or deactivated his account altogether since then) he stated that he was rather self-conscious about it.
* ''MyInnerLife'' appears to be this for Link's Queen. She now derides it as something stupid she did when she was younger, and hates talking about it.
* Creator/CoriFalls apparently laughs at her old stories now.
* John Nowak, creator of FanFic/TheNowakverse, began his MST of ''Under The Bridge'' (the first story in the series - which he wrote!) by describing himself as someone who should never have written Rescue Rangers fanfic. He would go on to insult the story in other MST works, as well.
* Stephen Ratliff, creator of FanFic/MarissaPicard, was mostly enthusiastic about his creation... ''except'' for one story involving her. One MST of the story "Time Speeder" opens with a quote, taken from a ''Franchise/StarTrek'' discussion group, where Ratliff states he never should have written "Time Speeder".
* Part of why Cyber Commander wrote a remake of ''FanFic/YuGiOhTheThousandYearDoor'' was to purge it of the character Wanda Underwood, whom he came to despise for being a needless TakeThat at Weevil. There were other parts of the old version he hated, like having Raven use a Dark Scorpion Deck with three new members on the team (violating the FiveManBand status of the group). He has also forbidden any other authors from using those cards.
** Also, in regards to his two ''WesternAnimation/CodenameKidsNextDoor''/''WesternAnimation/PowerpuffGirls'' crossovers (which have since been deleted) he pleads temporary insanity.
* Edrobot, of FanFic/JakeEnglishsMysteriousTheaterOfScientificRomanceFromTheYear3000 once mocked the rediculous crossover FanFic/HinataEndsWithTheSoulCalibur in an MST, only to reveal at the very end that he was the original author of the fic.
* "Sonic The Hedgehog: The Series". The author has pulled it from all online sources and deleted personal backup copies. It no longer even exists and the author has stated regret for spending time on it.
* This is how Blaze, the author of the original ''Fanfic/TheConversionBureau'' story, sees his work. The idea behind the story was to explain his own personal hypothesis as to why Equestria has no humans (with a little bit of personal WishFulfillment tossed in), but his inexperience as a writer [[GoneHorriblyWrong made the story]] come across as [[CantArgueWithElves incredibly]] [[{{Anvilicious}} anvilicously]] [[HumansAreTheRealMonsters misanthropic]]. He gained his own personal {{Hatedom}} and [[NeverLiveItDown an accidental reputation]] as a MisanthropeSupreme, so much so that he dropped the story entirely. More recently, Chatoyance, with her [[MarySuetopia even]] [[DesignatedVillain more]] [[SmallNameBigEgo questionable]] [[InNameOnly writing]] [[DanBrowned abilities]] and penchant for causing {{Flame War}}s, has far overshadowed him, which allowed his side of the fic's meta backstory to become more noticed and the hate to ease up.
* Avenging Hobbits, the author of the ''FanFic/HarmonysWarriors'' series, decided that the original version of ''Iron Mare'' was of such poor quality that he declared it CanonDiscontinuity (even using the term), removed it from [=FimFiction=], and rewrote the whole thing.
* [[FrolloFreak Frollo Freak/CrazedWriter]], creator of ''FanFic/BackToTheFrollo'' and ''The Disney Seven'', very much hates her "[[SelfInsertFic Claude and Me]]" fanfics(based off the villian, Judge Claude Frollo from Disney's [[Disney/TheHunchbackOfNotreDame Hunchback of Notre Dame]]), and admits they were awfully Mary-Sueish and poorly made:
--> (On her old Frollo fics) ''"Warning! The early stuff e.g., the "Claude & Me" series is blatantly and awfully Mary Sue-ish. I hate it."''
* Despite gaining a fair amount of praise, Steve Worek, creator (and mostly unseen co-star) of ''TheRockyHorrorPictureShow'' fan film "Bedroom Scenes" generally scorns any discussion of it. The theme song for the upcoming sequel, sung to the tune of 'Science Fiction Double Feature,' urges viewers to forget that "Bedroom Scenes" exists.
* Frustratedstudent, the writer of the ''LesMiserables'' fanfiction "A Thenardier's Redemption" was mortified enough to do a rewrite of the entire thing, and pleads youthful innocence for some of the events there.
* [=SiFi270=] has disowned ''FanFic/SnowAngels'' and deleted it from fanfiction.net, and will mock it in his later fan fics every chance he gets. As far as he is concerned, the RecursiveFanfiction written by Racke is infinitely better.
* ''FanFic/PrettyCurePerfumePreppy'' is one of the most famous and polarizing fan fics in the entire ''PrettyCure'' fandom. It was so famous that it started a trend of people making their own fanseries. At first, its creator, [[Tropers/PerfumePreppy Cure Shabon]], was proud of it. But after many years, she now realizes how cheesy and flawed it really is, and doesn't consider it her best work anymore.
* Despite receiving near-unanimous praise during its active phase, the "{{Metroid}}" / "TheLegendOfZelda" crossover fanfic "Life of Samus" has become its author's standard for terrible writing. Every instance of it being mentioned now is in an overwhelmingly negative context.
* When he was 19, MaxLandis wrote a SuperMario fansript. When he released it for download on his [[http://maxlandiswrites.com/super-mario-world/ site]], he added a few pages at the beginning emphasizing its problems and how much it sucks.
* The author of ''Fanfic/WeissReacts'' once wrote an old Crossover fanfic about Weiss meeting various rich and fallen nobles from other media, before abandoning it due to its low quality of writing. He left it up for posterity, but doesn't respond to the rare request to continue the fic or any questions about it.
