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:
[email protected] does not have illegal content
Checked the stickied post and it is full with links to various piracy sites. This is like when trackers use "We are not sharing files, just links" defense.
