The largest piracy community is hosted over at [email protected]
lemmy.world has blocked it. It appears to have also blocked [email protected].
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:
Doesn't this show the whole point of federation? That the owners of the community can pick and choose what they want their community to have access to, but it can't take down anything not on their own instance? LW defederates or blocks a specific community, the people who care migrate to another instance or just access that blocked community directly, everyone moves on.
