Free PHP Scripts by Gscripts.net

AdLogger intends to prevent click-fraud on your websites by limiting the number of clicks your visitors may make. AdLogger tracks AdSense clicks in real time and compiles the data for you to review.

In addition, the script determines if ads should be shown for a visitor depending on their clicking history. If one of your visitors is clicking too many ads, the script will automatically disable ads for that visitor so they won't be allowed to click any more.
