How to create a safe test campaign for your account ?

I understand that ads are banned when running on a new account. New accounts that have not spent any money in their accounts are often sensitive and Facebook will pay more attention. You need to spend a certain amount of money in it first, and do it slowly.

Not only images but also text and other elements affect your ad being rejected, you should check all the content including text and text. Another thing is to pay attention to the account, if it still doesn't work, you can try switching to another Facebook account to run

Your ban likely stems from excessive testing of new accounts and over-paranoia. Simply relying on organic images won't be enough to resolve it. To recover, keep your account active by posting from your game page, and run small-scale tests on a stealth blog with a $5/day budget. You can also involve your team to generate 50-100 fake organic interactions to help lift the ban. Start with traffic from one game page—test with a $50 budget for a 1K reach, then adjust as needed.

if your ad account is new, make sure it is fully set up and actively engaged in a non-spammy way- such as like, share, and comment on other users’ posts before jumping into advertising...or i think you can consider using other accs with previous spendings will be healthier
