That's where the majority of click fraud comes from.

Yahoo has been known for years to be in bed with scums. Nothing new there. 2nd tier ppc are the worst. And Google is not above reproach either.

Sometimes your ad is shown through spyware and you wouldn't even know it. Sometimes people see your ad, and sometimes they don't, but you still get charged for the click whether they do or not. There is so much more to ppc...

All ppcse's have incentives to keep these scums there, it's money directly in their pocket. Advertisers bitch, complain, sometimes even get reimbursed a few cents here and there.
