There weren't any, it was just a troll account that asked admins at a bunch of different Lemmy instances to block anything related to piracy. Lemmy.world admins took the bait. Even in the original announcement they never mentioned anything about dealing with tons of takedown requests. In other words they were blocking piracy related content preemptively before any takedowns occurred.
It's nice they walked back that decision but I'm still not going to create an account there.
Seems like another scraper site from therarbg team (they also run clone sites of TPB & others). Might be interesting if this one does indeed go independent & does its own thing.
