As a part of this evaluation, I have visited Google’s campus three times, examined various internal documents, interviewed several Google’s employees, have seen different demos of their invalid click inspection system, and examined internal reports and charts showing various aspects of performance of Google’s invalid click detection system. Based on all these studied materials and the information narrated to me by Google’s employees, I conclude that Google’s efforts to combat click fraud are reasonable. In the rest of this report, I elaborate on this point.
The 47 pages of elaboration are quite interesting. :)
The "history of google's invalid click detection efforts" bit, specifically the approximate dates of new filter rollouts was very enlightening.
I also had not heard of "Conversions-Per-Dollar" as a metric that Google uses to determine effectiveness of different web properties. A lot of the information in there might be of value to Adsense Publishers, too.

Yes, and that's why I posted a reference to the paper (including links to this thread and your profile) at:
The AdSense forum needed its own thread, since AdSense publishers are likely to focus on a different section of the paper than AdWords advertisers are: namely, the section that discusses publisher terminations for invalid clicks.
Bailing water on the titanic, I'm sure the bailers made a reasonable effort but the ship was fundamentally flawed.
There is no hard data that can actually prove this statement.
The guy had no real data, just happened to believe what he was told by google, not so sure that this document will help or hurt google, although lengthy, its all anecdotal.
