It's a crappy announcement. I understand where that admin is coming from, I understand why it seems reasonable to block politically-specific communities (well, if they weren't explicitly 'for everyone'). But it's telling that even their own users are saying 'that's dumb'. Not to mention the internal contradictions.

^even a user on the instance that pre-emptively blocked lemmygrad is seeing the problem

At least we can fill up the dunk tank with it. Our mere existence is a threat, it would seem.
