Its been a long time since I did anything with Facebook. Decided to try it again with a legitimate offer, very basic pics, very straight forward text. Not dating or anything scrupulous.
Its a new account. Created 20 ads. 20 ads disapproved for "content". Ok. So unless they tracked my IP to an previous banned account from two years ago (I don't even actually know if my previous account was banned) I am assuming that sometimes they just disapprove legitimate offers now?
What offer was it?
they never have consistency in approving & disapproving ads. Just keep submitting every 6hours if it's legitimate and I believe you will hit another reviewer that will have them approved.
Besides, do check your offer url at http://mywot.com to ensure it's not blacklisted.
They disapprove legitatmate ads/campaigns all the time, and vice versa so it really depends. What was your disapproval notice?
They won't track your IP and ban ads based on that, but they may do that for your domain if your using the same domain.
Little known fact, facebook uses dipping bird toys for it's reviewers.

It's the luck of the draw whether you get a toy hitting the N button or the Y button.
