I almost wish it were feasible to make a "Request for De-adminship" where someone could be nominated for admin removal as a result of a user conduct RFC, but then I realize what a trollpit that would become in a matter of hours. Arbcom is really the only way to take away admin rights with any measure of civillity and rationality. And they are swamped.
Maybe we need to be thinking harder about how to improve Arbcom.
