.world pre-emptively blocked the piracy comms because they are ostensibly based in Germany and have to abide by EU rules re: promotion/discussion of copyright infringement.
Despite the fact that they were never even issued a warning for such an obscure internet forum, and plausible deniability because the content wasn't even theirs, they thought it's better be ~~paranoid~~ safe than sorry.
ETA: so now .world has a stricter and more draconian policy regarding the discussion of piracy than Reddit, a publically traded entity based in the US, which has even harsher copyright infringement laws.
