My policy on players who obviously try to fool me as an admin, or come to me in order to get around the decisions taken by other admins, is very simple. It is quick, effective, and dispenses with having to waste 30 minutes that can be spent on more important tasks, such as helping new players.
Once I prove someone tries to fool me or use me to get around another admin, I ban them on sight.
The same goes for players who try to flame and shit admins outside of Argonath domains, players who scam new players by using their inexperience, and regulars who continuously moan / provoke.
