i'm gonna agree with spasm here. i know the feeling when people are accusing someone of walling and you're like OOOOO GOODY I GET A BAN! but like spasm said, watch your demos, and with an open mind. ran across this situation in pub a few days ago, eeeeveryone was saying this guy was walling so i went to pull the demo and ban him, but there was 0 evidence.
also, don't put a 3rd option in the poll. everything boils down to either ban or unban, a 3rd option just clouds everything up.
