As a casual AdWords advertiser, my perception is that Google has gotten better at controlling the fraud so click fraud is on the decrease with AdWords, not an increase. Sure I'd like to have a better ROI than I'm currently getting, but it's already pretty good. It's a dead story for G advertisers, as we pretty much have the system figured out and if it wasn't profitable, we wouldn't be doing it. For the 2nd and 3rd tier, that's where the story is.
