I was waiting for my admin application on a server, then some guy joins and tells us he is Jesus Christ, he told us that the world was going to end tomorrow, on 12/22/12. The owner banned him. Soon after another account joined which also claimed to be Jesus Christ, who the owner also banned. This happened three more times until he was IP banned.
A few days later, I was a server mod. It turned out that the server admin was the guy pretending to be Jesus. He greifed the server, and was then also banned. (I then took his place as admin )
