Unless it's a TOU violation, local admins can pretty much do what they want. If they're extremely abusive, they'll only drive people away.

Though you could argue Wikia could take firmer steps here, but I'd imagine that function will be used by just about every blocked user. Take a look at every local admin's wall here. It's all "why am I blocked do you hate me you're mean". If Wikia has to deal with that, they'd waste so much manhours they'll have to start charging for the service.
