if only it were that simple
the then banned member, just signs up with another "free" service provider, a hay presto, they have a new ip address, then re join as a new member
or
if a member is regested with an aol account, they use one ip address for multiple users, we ban one member, it could take out a further 100 plus good members
the way forward, is for members to use the "REPORT" button more, keep us informed, and then rather than starting up posts, that get everyone crying "anti" an eye can be kept on them, and if need be, deleated, ceratain ex members do try coming back
