FanFiction.Net is the self-proclaimed "world's largest fanfiction archive and forum" and is one of if not the largest site hosting fanfiction. Has a sister site Fictionpress, much smaller, identical layout.
It is in the process of being preemptively archived.
Most of the work is just staying on top of the new stories and user profiles.
The Archiveteam's 2012 scrape of the site can be found on Archive.org (in 18 parts, totaling about 830 GB).
A nearly-complete scrape of all stories on the site, in text-only format, was created independently of the Archiveteam project in September 2015 by bsmith093 on EFNet. It was later repacked, and is now available on IA: fanfictiondotnet_repack. (The original version was uploaded under the ID FanfictionNearlyCompleteArchive and accidentally duplicated by a different uploader under the ID fanfiction.net_2015_09).
Profile IDs are being scraped from indices; downloading will then occur on a per-profile basis. Drop by the IRC channel EFNet #fanfriction for more information.
