Whats a good hitbot protection script?
 

I have a mainstream program that pays per click and of course im getting a decent ammount of click fraud from some affiliates. Usually i can spot them easily but some are smarter than others and don't send all 500 hits within a minute. Anyways i was wondering if there are any scripts out there where you can import a big proxy list and block those ip's from accessing the site. Or if you can code something like this please hit me up on icq.

you can block proxies through .htaccess too
