The point is, it doesn't MATTER if it's not my fault.
If I'm an advertiser, and I'm advertising on your site, I don't care if it's you clicking on them or your traffic - if they aren't real clicks or they don't convert, I'm gonna be unhappy. And I'm gonna either block your site from showing my ads, or complain to Google. And I'm sure not gonna want to pay for them.
(I think John just deals with Traffic Quality and not all the other AdSense issues, like the ads)
