I'm no fan of piracy - just seems like a pretty name for petty theft to me - but this decision seems problematic. I went and read some of the threads about this decision on some of the other communities, including dbzer0, and I looked around the blocked communities on an alt account.

I'm not seeing evidence of actual copyrighted material posted, just discussions about how to steal content, which itself isn't illegal. And there's a pretty fair amount of content - the communities are active - so if there was a violation I feel like it should be handled as the exception it appears to be. Those communities themselves don't allow posting of copyrighted content, so it shouldn't be a problem to get a violation removed. If someone posted an image that contained child pornography to one of the NSFW communities, would we block the whole community, or just get that post removed (and alert the authorities)? The latter, I hope.

They also make a good case that the action was taken in response to a troll on a newly-created account who didn't provide any evidence of there being copyrighted material. That in itself seems like a problem, though maybe someone looked into it? I'm pretty supportive of the .World admins, I think you're doing a good job in a difficult situation, but I believe these communities should be unblocked unless there is an actual problem.
