If lead quality was so bad across the board it would be the same for everybody so bid prices would fall to a point where Y! would be hurt very badly but I don't see that happening at the moment. Either way, the market will decide. Click fraud unfortunately is a fact of life but I'd be surprised if any appreciable number of affiliates were involved in that because if they were caught out their businesses would disappear in a puff of smoke and all the SEs are getting more sophisticated at detecting it. Now competitors and bored kids - that's a different story, and how long would it take a half-decent programmer to write a viral script to make infected machines click randomly on PPC links? I've been expecting the demise of PPC for some years now and it's replacement with some form of CPA which I reckon will have to come sooner or later.
