"The Subspace Emissary's Worlds Conquest", a "Super Smash Bros." fanfiction written by FanFiction.net user AuraChannelerChris, gained media attention for its length of over three and half million words at the time of notice, more than three times as long as "In Search of Lost Time" written by Marcel Proust, and is still being written. The longest fanfiction on the site is "Ambience: A Fleet Symphony", a fanfiction of "Kantai Collection", which is almost four and a half million words long. Fanfiction.net contains some fanfiction works of considerable length. Some of them, like "Ashes of the Past", are over 1.000.000 words long. Those stories are normally written on over the course of many years. The table below lists notable fanfictions of different categories with more than 500,000 words to boast to its name and has a large following of fans. FanFiction.Net instituted several policy changes as it grew in size and popularity. These policies frequently led to the deletion of fanfiction based on the copyrighted works of certain published authors or containing specifically targeted content. Since the site's founding, several professional authors and producers have asked that stories based on their copyrighted or trademarked works be removed, including Anne Rice, P. N. Elrod, Archie Comics, Dennis L. McKiernan, Irene Radford, J.R. Ward, Laurell K. Hamilton, Nora Roberts/J.D. Robb, Raymond Feist, Robin Hobb, Robin McKinley, and Terry Goodkind. In addition, stories based on real-life celebrities were disallowed around 2003. Fan fiction based on professional wrestling, however, is still allowed, being the number one fandom in the "Miscellaneous" category. On September 12, 2002, FanFiction.Net banned and removed material that was rated NC-17. Prior to the new policy, the site would use a pop-up to prompt readers to say whether they were over 17 or not, but since then, the site has relied on its users to report stories that are inappropriately rated. Some NC-17 material was moved to Adult-FanFiction.org (previously AdultFanFiction.Net), a similar site which was created to serve the adults who write R and NC-17 rated fan fiction. However, many stories containing explicit material still exist and have yet to be removed. Story titles and summaries must be rated K. These have been banned since 2005, and the site removed all material that had the potential of inserting the reader into a fanfiction.
