Sorry if already discuseed, but I couldn't find any threads on this product at webmasterworld.
I saw a demo of www.whosclickwho.com at SES New York and thought I might try it. I know you can do some of this stuff manually, but we liked the idea of an automated service, and the pop-up window as a detterent.
Seems like it would only deter competition fraud, and not affiliate fraud. Has anyone ever seens any stats on how much PPC fraud is affiliate vs. competition?
