Here is the idea. I want to get someone banned from adsense. So what i do is go around on forums and post topics telling people to click xyz.com's google adsense ads. Then I go and buy some traffic to the site and click bomb the site (plus do alot of other things to flood the site with fake traffic + fake clicks). Then I go and report the thread posts to google saying that xyz.com is asking people to do click fraud on their site. Google would investigate the situation and notice lots of odd traffic + huge increase in clicks. What do you think google would do?
