Hi, I've started a few proxy sites and I have been wondering if there was a way to prevent fraudulent clicks? Last thing I need is someone clicking on the AdSense ad few times and getting my account banned. Ages ago I used a script that made sure multiple clicks were not made, but I have been unable to find it again.
asrep will log the IP of the faudulent user and you can report it , in the paid version you can prevent more than x clicks from an IP.
