About 4 years ago groups of people were defrauding "paid to surf" companies such as AllAdvantage and Paid2Surf. One of these groups was SoAngels. I was a part of this group and we coded programs that used gigantic lists of proxies to emulate clicks or views on ad banners. With a lot of the new technology though, this type of "cheating" died out. Most companies now check the origin of click (Country) to see if most of your traffic is from outside the United States (a typical red flag for cheating considering most proxies are offshore). Companies also check views to clicks ratio and compare it to the average that other webmasters have. If emulated properly using Winsock controls, it is difficult to tell that the emulated click isn't legit/real. If Google implements the above, only people with gigantic lists of USA/UK proxies that don't have "proxy" or another dead giveaway in the hostname can get around this. Timestamps also work well. If an insane amount of clicks come in a relatively short period of time, then flag the account. For the brilliant minds that run Google, this should be a cakewalk.
