NEVER refund adminlevels, EVEN if the player claims he was admin on one well known server.

There are really thousand of reasons why not. They aren't familiar with your script, you don't know the reason why he left the adminteam on <well known server>. Maybe he wasn't admin there at all!

My advice to you is: Stop ALL your statrefunds. Your RP server isn't gonna be very good if you keep doing that.
