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
edit:
An official announcement has been made:
It’s a volunteer ran instance and the first rule is no illegal content.
Go find a different instance if you’re so butthurt.
