Well how google sees it, say the cost of the click gets split 50-50 between the publisher and google.
The publisher doesnt get paid until they reach $100 so by that time google has made $100 off of you, then they look a your account, if you have been doing fishy stuff they ban you, keep the money so they have made $200 from you and not done a thing.
Google is in a win win situation because they charge the advertiser in the first place, then take half of the publishers revenue then more then likely keep it if the publisher gets banned.
So clever how it works
