E power trader used to have this feature where it could block ips with htaccess if you wanted it to. You could tell it how many times an ip could enter the page in 24/hr period or how many clicks max from the ip in 24/hrs then it would block the ip through htaccess for your determined amount of time, or forever if you wanted. I liked that feature a lot because it helped to clean up traffic. It would be even better in TP where it could block across an entire network.
