I was banned by Google. I had earned just $100 over a 6 month period for one of my sites and they banned me and never told me why. I asked to be reinstated recently and they refused.
Its really bad to hear that you were banned..but were you engaged in click frauds or had you violated any of TOS. They don't ban you without any reason.
AND you were banned by DP also. soon to be banned again.. http://forums.digitalpoint.com/showthread.php?t=1069501 http://forums.digitalpoint.com/showthread.php?t=1070611
