I had a guy once that made himself out to be my #1 supporter and said how we was so fair. Well, that lasted for a whole 2 months or so. then he began arguing with members he didn't like. He would close threads of complaints towards him and post the final comment aimed at the aggressor, and the list goes on and on. It came time very quickly for me to let him go, and it was then that he blew up. My began spewing lies and rumors on two semi-competing sites. While it was bad, it didn't affect much and the community was much better for having him gone.
