[VBUsers]

on my board i have a couple of childish kids posting racial remarks and insulting people for no reason. i know who they are but everytime i ban them they come in and sign up with a new name. i know about the proxy thing and the IP stuff but what can be done so i just keep that person out and not the other members with the same proxy IP. thanks in advnace for your help

It works the only thing is if they are using high anonimity proxy's and their ip address info isn't forwarded it won't work.
