>Fandom purges are almost never just about one thing. Fannish content both relies on fair use exemption and is frequently sexually explicit, so it gets attacked on both copyright/legal grounds (thank you, OTW Legal Team, for protecting us!) and TOS/hoster rules about porn/specific fictional content (thank you, AO3, for being an open archive!). On top of that, there is a nontrivial history of fannish content being lumped in with content that criticizes authoritarian governments, and targeted by sweeps by those governments and their censorship agencies when they purchase or put pressure on the commercial entities that own the servers (thank you, OTW, for being a nonprofit and owning and defending our servers!).

>If you care about fannish content, you have to fight for fanfic on all three fronts. And if we hop off of HTTP and onto one of the decentralized protocols like dat et cetera, like people are starting to talk about in response to Article 13 and the Tumblr purges, we will inevitably be targeted along with a) people pirating media, b) porn distributors, and c) anti-government protestors, because those groups are also going use those protocols, too. I’m not saying, don’t think about migrating. I’m saying: there is a systemic problem within fandom, regarding the fact that we routinely get hit on three fronts: legal rights to the material we transform, sexual content, and governmental disapproval. Protecting fandom means fighting for fandom on all three fronts and putting thought and effort into how to make an archive robust against all three prongs of the attack.

>This is what’s made AO3/the OTW so special: we have lawyers protecting our right to make what we make, we have a TOS that protects our right to make things that are sexually explicit, and because the OTW is a nonprofit, it’s more robust to the pressure that can be brought to bear upon commercial entities by both corporate and governmental powers (though, I note, especially when it comes to governments, it’s not immune, and we have to keep actively protecting it, and we have to protect other fans). If you are in fandom but you think that copyright upload filters are fine, because, well, you don’t want to put fanvids on YouTube, you are part of the problem. Your community is under attack. The powers that be have always come for us by attacking us in pieces, and we have always only ever successfully fought back by banding together.
