I'm a member of AO3.
Apr. 30th, 2019 11:39 amAO3 is managed by the OTW (the Organization of Transformative Works). I pay them money. You should too. You know why?
Because back in 2007, we had no archive of our own. We pretty much only had Fanfiction.Net, which purged a great deal of explicit fanfic back in 2002 (and might very well do it again any time), and Livejournal.com, which booted a number of journals in 2007 following a targeted attack by a religious organization. Although AO3 is far from perfect, it's run by fans, for fans, and has legal language to back up the rights of fans to post transformative works.
Having said that, I also still post on FFNet, and I've never had a story taken down there (although I have friends who have). Here's a partial explanation of why.
You can read more about OTW's history at the Fanlore wiki, or this article from 2015 in FanSlashFic Magazine.
