It can be fun in a small circle, but if an Admin uses out-of-game methods to support his cause, it's cheating and NO that should not be allowed.
I remember playing Counter-Strike on a public server, where the admin would broadcast public messages to inform his teammates ("the bomb is at point A") AFTER he had died or kick enemies in a crucial situation just to have his team win.
It's obvious that this ruins the game. It's not a big deal in small games like CS, but in MMORPGs this is a big issue where admins should not be allowed playing if they can't play fair.
