You don’t own fanfics. They’re inherently public domain because they aren’t your IP. Agree or disagree with AI, there are no grounds for “protection” from AI because it isn’t your IP to begin with. That’s what you chose when you chose this medium

Do I, or any fanfic author for that matter, have any legal claims to our work? No, not really, no. (Although if someone took a fic, filed off the serial number--deleted the fandom specific elements--, and then had it published for financial gain, yeah, that would be a case.)
