You think that there is no click fraud on the search network? Of course, there is. Advertisers are fraudulently clicking competitors' ads in order to waste their budget and edge them out of the ad auction.

I think you should go back and read things I have written over the past few months on the subject of click fraud. I am fully aware of its existence on both the search and content networks, and from the standpoint of the publisher, advertiser, and search engine/ad network.
