First time I get a warning email then I immediate move all my sites to parked (scary me). Wait for sometime then only slowly move back. A few months later, they banned me without warning. Why I said unknown reason, because I don't do anything against their policy. Never click on own ads even I saw any interesting ads I will right copy copy link location then cut all argument from the link and paste into address bar. But I recall back, maybe is because I press too many times reload when redesign my sites or someone attack me to get me ban.
