I would suggest that click fraud would be as high as 40% in some industries, and as low as 0.01% in others. Some industries just attract fraud based on high CPC's..high volume...etc. Overall, everything averaged out over millions of clicks, perhaps it is as low as 5%?

I'm of the thinking that if they are actively trying to contain it, or stop it, then one must for now factor it in as an everyday cost of business. If your ROI isn't measuring up, you drop your bids...and vice versa.

I do have a problem with how they answer controversial questions, as though they are trying to hide something...
