I was banned a couple of weeks ago...it wasn't for the rebill ads I had, it wasn't for the risky dating ads...
It was for creating TOO many ads with in a certain amount of time. Which shocked me because that day I only duplicated 80 ads that were on auto approve through out the whole day, it wasn't in one shot.
It's some auto detection thing they have in place that will auto ban you...
They also said I was warned before about it which I never had been...they turned my account back on.
