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'm really not a fan of the lw admins just blocking communities. It's not the first time either. It's even worse than defederating, because there's no record of it.
I signed up to lw on its almost first day, but with some of these policies, and constant downtimes, looks like I'll be moving. It's a bummer I've created all the communities here before lw became so big.
