Don’t worry about getting your ad account banned,
because is as easy as getting a new debit/credit card into a new account.
If you use the same card number, on a new account, you get auto-blocked.
But - If you go to your bank, and get a new card, which they will deliver in 3-7 days. Problem solved
The marketing data will be lost, but the fb fanpages can be merged into the new ad account.
The way to prevent marketing data lost, is to run simultaneously 2 different ad accounts with 2 different cards numbers and 2 different pixel codes.
I did it. I get baned. and is no big deal to get back in the game again in 7 days fast.
Hope it helps to reduce the anxiety, fear and the worry because I had that too.
