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:
About lemm.ee . . . it's a great instance, no doubt, but maybe not the safe haven you think it is. The rules there leave the option of blocking "illegal content" and users/instances that post it wide open.
Excerpted from the Administration and federation policy on lemm.ee (the bold is their own):
I don't like to piss in other peoples' Wheaties, just trying to save you and others some trouble. If you're looking to change to a piracy-friendly instance that will remain so regardless of how "illegal content" is defined at any particular moment, lemm.ee might not be it.
