Bureaucrat
A bureaucrat neutrally executes a process without involving any of his or her own judgement except in minute details.
Wikipedia used this term briefly to describe those with sysop status on more than one project, who are trusted to execute the sysopping protocol (how sysops come into being, and cease to exist - although the latter NEVER happens on Wikipedia which is run by a cabal devoted to denial of their status:TINC).
There was a list of them at m:bureaucrat. Supposedly, they lose this status for abuses. But since the list includes several known abusers (Daniel Mayer, "Angela", Tim Starling and others) who always support the sysop power structure or usurpers (like the developers) there was a risk that one of them would lose bureaucrat status. Accordingly they abandoned this term and the commitment to follow any rules, then attempted to cover up by, among other things, attacking this article to remove all mention of their attempt to make their power appear legitimate. See also 142.X.X.X/Flames for some of these issues.
The British TV series "Yes, Minister" and "Yes, Prime Minister" are about the way bureaucrats steal power.
Consumerium may be able to more correctly implement this with a political faction level that would actually put representatives of the users (and to a lesser degree the contributors) in charge of the bureaucrat activities.
