"A sysop can only be "promoted" back down to regular editor status if they request it, or if they are causing trouble through serious vandalism, troll behaviour, or abuse of sysop abilities such as blocking. Complaints of this kind should be raised at the Administrative Abuse page, and the decision to "promote" the sysop should only be reached after a full discussion."
