Edit: Guess I should explain this more.
While I was out of a job, I figured I'd try out AdSense to see if there was any kind of revenue to be made from it. It was up for a month or two and generated something in the 3-digit dollar range. Not a huge amount, but more than I expected. I figured I'd stick with it. Then I got my job at Red Storm, and after I moved into my new place and got an Internet connection set up, I noticed the ads were blank. I thought maybe it was just something with my browser, or something about the new internet connection, so I wasn't too concerned until somebody else mentioned it. When I tried to log into the AdSense account, I found it had been disabled completely. There was an auto-generated email in my gmail account similar to the one above. I tried appealing, and after waiting a couple of weeks, got the message above. I didn't get any of the money.
Searching around, I found a number of other people experienced the same thing. Some people were set back thousands of dollars. Apparently google has an algorithm that checks for "invalid" activity, then shuts the account down without warning or explanation. I have no idea why it was disabled. I can't even log into the account to look at the statistics.
