Mostly just joking, it's more the appearance of what was done than whether or not there was any unjust pecuniary gain by the goog.
Anyhow, I'm up to having spent $1,200 on adwords since December 1 (Took a week + off for X-mas, etc., so I'm combining December/January), so believe me I'm all about them going after some click fraud.
What's particularly bad, is I'll have 50 clicks on ad X in one day, but the next day's reports only show 30-40 uniques from that ad, yet I have never received an "adjustment" as a result of their having caught click fraud.
However, the day they can effectively catch it all will be a help for everyone.
