Everyone keeps telling you to run policy-compliant campaigns on FB "Facebook".
I do not get it, this is a BH forum "BlackHat". So here is my advice.
Review all the campaigns you have already run. If too many were rejected, your BM may have been affected, depending on the severity.
First, launch a clean warm campaign. Use just one image and the simplest possible text.
Then watch to see whether it gets rejected again. If it does not, let it sit for a long while, then replace all the content in the campaigns you actually want to run.
Be careful, careful, and even more careful.
Another possibility is that your BM has a hidden ban. There are different kinds of hidden bans. For that, you should contact Facebook Support.
Bottom line, The easiest way is to switch to another BM or ad account. It will save you time and effort.
Also, sometimes the fanpage, Instagram, or even the personal account you use to run campaigns will get flagged. Do not forget to check that too.
