Unfortunately a big problem is AOL. We still have a LOT of people on AOL (maybe 50%?) and for the most part their IP's change so much there is no way you could block anyone without just blocking AOL.
One could create an "exempt" table to store user id numbers then during the "check ban" function it would ignore the banned IP address if it's being used by an "exempt" user. Then a whole block of IP addresses could be banned and not affect trusted users.
I have done something simular for other purposes and not with php for a website. It works well.
