I must admit I've not seen this yet. In the forums I frequent the old elite rules...to the point where the admins trust the powerful members to manage it to some extent. If 3 powerful people decide that a new user is undesirable then said user is a dead man walking. Obviously not very democratic etc...but its super effective in maintaining the peace....the powerful members provide a base-line that absorbs most of the BS...the admins step in when something dramatic happens.
