Ad Sense click bombing is the malicious practice of generating high volume of clicks on AdSense ads on a competitor’s or opponent’s website to obtain his banishment from Google AdSense program. The victim is then banned and his account closed due to invalid clicks.
It is almost imossible to prevent click bombing for AdSense members, but it is possible to try to prevent the banishment. Abnormal click activity has to be quickly discovered and when it occurs the website owner must contact Google through the invalid click activity form in his AdSense account. He may also temporarily block the display of AdSense ads.
