Hey, if that "adjust invalid clicks" link is what I think it is....That's my suggestion!! I once wrote an email to adsense suggesting that there be some way for publishers to "cancel clicks". That way, Google would have a way of distinguishing the publishers who accidentally clicked from those who were intentionally cheating...then they wouldn't have to ban people with a "broad brush"...could they have taken my suggestion to heart??? MySpace., you can thank me for adsense not banning you.
I think this is a good idea. The more protection for advertisers, the higher the payment will be to honest publishers. If this is implmented/already implemented, advertisers of Adwords are risking less and so can in theory bid higher since they get a larger ROI.
