Stevie: Thanks. I knew that part. But if they just left for the second time, and I dont want them back in, and they try to come back 6 months from now, but I dont remember by then that they have already been in and out twice.... (kinda confusing, i know)

I guess there is no waty to just go to their profile or whatever to ban them, just have to wait until they ask back in, and hope I remember then to ban them?
