Complaint Looftnarg (again)

I was just on Minecraft, at someones disco house, when the owner and creator invited Looftnarg, to be the DJ. As he arrived, he started destroying the signs, saying "nope.avi". After about two minutes of this, he went around marking the corners, and then erased the whole thing. He could bring it back, although he probably won't. Please reconsider keeping Looftnarg in op status, as he has shown himself as a griefer, simply because he didn't "approve".
