As a publisher I hate click fraud as much as the next guy, but as long as advertisers get a decent ROI, why worry about click fraud? If the ROI decreases, they will simply decrease the cost per click. It sucks for honest webmasters, but I just don't see the yearly panic every time they come out with their numbers to promote their product.

Personally, I think compromised PC should simply be disconnected by the ISP until it is fixed, especially those used in DOS or spam bot nets, a far worse problem.
