"Just curious whether moderators are peer reviewed by other moderators, for when they are obviously expressing their biases by deleting messages, blocking users etc. you know, abusing their moderator privileges to suit their own agendas."
Yeah, this happens, but I highly doubt there's a "review". This would be a funny thread if you got former staff to do a tell-all expose‘.
If you make your own site, I'm in. You should also seek out Vipera to be a mod on the-one-day-coming website--there's no way that guy will become corrupt.
