Just so you know, there’s a neat Piefed admin feature to add a note above the comment form for special communities. For instance on piefed.social, Rimu has added a reminder to respect the “be nice” guidelines on beehaw’s communities. WomensStuff could use that 😊
I don’t know if it federates though, you might need to individually ask server admins to add the note on theirs.
Mangadex got a DMCA notice recently, which resulted in a huge takedown. Something like 25% of their chapters I read somewhere.
