This is all good and well on a big wiki, but on nv:
the only admins, and in
fact the only regular users, are the two involved people. The only other
admin that could have been asked was the blocking admin himself, the proper
channel would be to get agreement between all blocked users - half of which
are the person being blocked, the other half the person doing the
blocking...
Well, that's another matter entirely. It's a case of there not being
enough admins for them to provide checks and balances for eachother.
I'm not sure what can be done about that...
