That’s not a copy of the main piracy community, that’s another piracy community that’s hosted on lemmy.world
The community people are talking about is !piracy@lemmy.dbzer0.com, which is no longer accessible via lemmy.world
It appears !piracy@lemmy.ml is also blocked.
!piracy@lemmy.dbzer0.com
It’s blocked from lemmy.world. I’d recommend using LASIM and migrating to another instance like https://lemm.ee/ (note: you will need to manually resubscribe to !piracy@lemmy.dbzer0.com on your new account, since LASIM won’t be able to see it).
