You're missing that ad networks can detect and exclude these spammy clicks. And on many networks advertisers can choose to be charged on a per-conversion basis.

Google claims this because their entire business model relies on people believing it but is it actually true?

I used to work on ads at Google, and knew folks who worked on invalid traffic detection. They seemed to spend most of their time on much more subtle sorts of problems, so given how simple AdNauseum is I'd be surprised if they had trouble filtering it out.

Curious how they can detect this. All the see is a GET request with your ip and ua. Perhaps if they see too many they can flag your ip.

They get quite a bit more than this: look at what's sent with an ad request some time!
