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:
No, that is the whole point of federation. The admins of an instance have full power over their own instance, but nothing else. That was the entire design of the fediverse. Anyone can spin up their own instance and curate it to their hearts content without affecting anything outside of their instance.
No shit the admins of an instance have the ability to unilaterally remove access to a community. It’s their damn instance. That’s the point of everything. Join an instance that shares your values, or make your own little instance with only you as a user and federate with whatever you want to federate with.
That’s the design of the fediverse.
