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 don't care. I browse my own subscriptions and ignore c/all. Problem solved.
I'd rather an instance that blocks too little (and therefore, has 0 effect on my browsing experience) than one that blocks too much (and therefore, does affect my browsing experience). I'm more than capable of blocking things myself if I want, I don't need my hands held.
