Nonsense, there are loads of those subreddits around.

Reddit bans doxxing, which I think is protected speech in USA, because it can be used to out people who run bigoted subreddits.

Your because is misplaced. Reddit bans doxing because of how often it is something they wouldn't want to be associated with. They do it to protect their image, not to protect some particular group of users.

(I agree that the ban happens to protect those users, I find it highly unlikely that this is a motivation for it)
