I think we all know deep in our hearts that hackers are out their stealing companies blind with click fraud. It is to bad really because a lot of people could use those dollars legitimately Ultimately two people loose, sites like mine and advertisers that are being scammed against. The only winner is companies that provide the service and take a cut.
Bottom line is Mark is correct and there is not a lot that can be done to stop it unless advertisers get smart and start contracting with companies that can guarantee that the sites their ads are on will not be stealing them blind.
