A week and a half ago we covered a topic we named Yahoo Laughs Off Click Fraud Report, soon after the thread was renamed to Click Fraud Report Gets Laugh From Yahoo Rep and featured on the Search Engine Watch Forum homepage.
Yesterday, Discovery, the thread creator, posted an update to the thread. He/She got a call from senior YSM Management, they provided a refund in in excess of the $6,000, and they asked Discovery to provide constant feedback on PPC fraud issues. So Discovery decided to start a new site named http://www.junkclick.com/ which is not yet active. At this site, "search marketers can submit their data regarding junk clicks. We will aggregate this information and provide results to those who submit data. Our goal is to provide the major ad networks with concise and timely information on junk click activity within their networks."
