Aside from the fact that the revenue generated by Google’s AdSense program would be rather miniscule, and because I wouldn’t be happy with the aesthetics of ads on this page, there’s another reason why i haven’t bothered being an AdSense client: click fraud.
Yet another reason why the ‘net is such a seedy place, and why sometimes I think people should probably be licensed before they can use the ‘net (no real tests, but if you do something enormously stupid, spam or click-bomb someone, then the license gets revoked).
