The largest piracy community is hosted over at !piracy@lemmy.dbzer0.com
lemmy.world has blocked it. It appears to have also blocked !piracy@lemmy.ml.
If this is a problem for you, I'd suggest migrating accounts using LASIM to an instance that doesn't block it (such as lemm.ee).
edit:
An official announcement has been made:
I mean its not their fault for trying to be proactive with this site gaining so much online traction. People are complaining, but they posted the named instances!!!!! They know its bullshit but they were like hey just go here and make a new account! It wouldve been different if they done this quietly.
