Sometimes you may get a staff member that may cause some problems concerning his/her powers. The staff member may ban someone they dislike or hold a grudge against for no reason. They may edit or delete posts at random. Have you ever had anybody like this? How did you handle them? I have never had someone like this (luckily). If I ever did, I would instantly revoke the member's powers. I would then talk a little to this member via PM. I may ask questions "Why did you do that?" or "Do you want to keep being a member of the staff?" If the member's answers sound deep and honest, I will wait a week then give back the powers, but keep a close eye on the criminal.
