I can tell you that I was caught up in this as well. I started serving ads for Google on my sites way back - near when the program first rolled out I believe. I was suddenly banned not long before my payout was due with no explanation about 2 1/2 years ago after serving ads on my sites for them for years. No appeal, all money earned was kept by Google, I never saw a cent of it. It made up a large portion of my income and not only did it suddenly stop, but the payouts owed to me were negated and my access to the adsense interface was closed so I could not even log in to get information on what was owed, what sites had what clicks, etc.

I 100% believe in what this person is saying as I know all my sites. There were no fraudulent clicks or schemes going on, it was all natural traffic and clicks.

This is yet another reason I stopped using Google and instead use Bing. I think everyone should stop using Google search and switch to a different provider.
