Thank you for reaching out to the community forums to share your issues with Facebook and your ad campaigns. I understand you are having issues with Facebook rejecting your ad campaigns and you aren't sure why.
While I can't speak to Facebook's decisions in this matter, I'm happy to go over your ad campaign with you and see if we can improve it's rating. In order to help, I would need to see a preview of the ad campaign including the image(s) you are using, the copywriting used in the ad and the landing page of the store (a screenshot is fine if you don't want to share the store URL). This will help me compare the ad to Facebook's Ad Attribute to Avoid.
Hopefully we can get this resolved for you!
