I'm not sure it's possible to hack Adsense, Webdev. With standard affiliate programs where you're given a link, it's easy for someone to swap it out and purchase with their own affiliate link but how would that work for AdSense?

The worst that could happen would be someone would try to steal your Adsense code from your web page but if they did that, you would actually earn the commissions. LOL So you would benefit. Unless I'm missing something not sure the stolen commissions apply to a program like that.
