As for click fraud in the CPC model, it's like shoplifting and employee pilferage in the brick-and-mortar retail world: Some theft will always occur, but the business model won't be threatened just because a small percentage of people steal and don't get caught.

I don't think the analogy is quite accurate. A more appropriate analogy would be if someone compromised an AdWords account and was able to add funds to it.

Since any business is a potential victim to compromising of its assets, it seems to me that any business that is a potential victim to click fraud is that much more vulnerable.

Bottom line: As long as advertisers and publishers are satisfied with their ROI from AdSense, fraud is an annoyance, not a dealbreaker.

Well, I can't argue with that.
