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:
In the real world there's these people called "Lawyers" who will happily sue relatively small, cash poor platforms like lemmy.world out of existence. What would you like the admins to do? Are you coughing up legal fees for them?
Discussion of illegal topics is legal in most of the world.
