I guess I disagree completely---under no circumstances should all sysops be able to ban any user at any time at their sole discretion. And having a rotating group I feel is far better than appointing a small group of sysops as permanent custodians.
Oh, sorry, I wasn't clear. I would be against having a small permanent group. By a small group what I meant is that if *any* three sysops agree they can ban someone temporarily.
