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 get it cuz corpos be sue happy lately but at least it shows the Federation's strength: simply having another account routes around the problem.
If this was reddit it'd be gone for good.
But here it's just a mild inconvenience.
