Well, I'm understandably curious. What was your "case"? How did you get a human to respond to you? In my situation, I emailed them immediately, asking what clicks were fraudulent, could they be filtered out, etc. The response was an auto-reply basically telling me to go away and never bother them again. So, another email, explaining what I thought happened (pretty much what I wrote upstream in the thread),with another form email response, similarly shutting me down.
Again, I'm cynical, but I have to imagine you got a favorable response due to your growth rate. Google is a business, and you make them a lot of money, I imagine. Someone saw that potential and decided to intervene and overrule their vaunted, flawless, secret algorithm.
I also find fault with the fact that they shut me out of my account, and yet somehow they don't have the technology to stop serving the ads. I had to manually remove the AdSense code, because even though I was somehow guilty of generating fraudulent clicks, they continued to serve ads to my site. It was alright for them to continue to make money from my site, but not for me to do so.
The system is seriously flawed. That said, though, I'm a hypocrite - given a hearing ear and a reinstatement, I'd host them again.
So my advice is, use it. See what happens. But don't be surprised if 2 days before the check is cut you get an accusatory email...
