I have seen a lot of people complaining about being banned from the Adsense program. On the whole I am sure you all know why you were banned so stop being so shocked. Google have amazing antifraud measures in place which protect users, advertisers and publishers from being ripped off. Good on them for trying to get the rampant online botclicking and advertising fraud under control. Now all they need to do is get the spammers out of their search engine listings.
