It looks like they are able to do that with the new message boards, but the boards are all cut up into too many categories to be useful. What they should do is to switch this board to the new software and just have the one general category. Even then, the primary method is to block ip #'s, but most people get a different one every time they dial up. Also if you block a "subnet" then you might be denying ALL of the members of a given ISP. Maybe the join function will help where one needs to login to post, although anyone could just keep joining under another name etc.
