My account was disabled one year ago. No warning, no reason. Then I contacted the customer service of Admob, after few days, they told me their system detected that my account has some issues. I lost hundreds dollar just because the arithmetic said I was criminal. And someothers told me, their system made mistakes sometimes. If you met, it's your own badluck. :(
