First-ever Click Fraud Shakedown?

A person who spends $200K/mo on Google, Yahoo and MSN driving mortgage and insurance leads in the UK told me today that he's enlisting a couple buddies to get $5000 back directly from one of Y!'s UK search distribution partners for impression/click fraud they committed via Y! Search on his campaign.

A high-volume PPC lead gen advertiser on the verge of shaking down a Yahoo search distribution partner in order to recover money stolen via click fraud? Maybe the search engines could incorporate that into their anti-fraud measures...
