Click fraud is there, regardless of what those that base their business on it say. For me, click fraud is anything that is outside of the scope of a regular searcher looking for information, including impressions and clicks coming from competitors doing a research on their opponents (a reason why I called to get AdWords preview tool make real links available on both paid and organic results).

On the other (aka Google's) side, to which extent any system can go in click identification and differentiation? A tough one.

Still, we want our money to be respected. Would you buy a car that spills gasoline around?
