At first i create Facebook account and then register facebook.com/ads but when i create my first ad and attach the credit card, after 5 minutes it has been blocked. It happened two times. Please, advice me how to create facebook ads not be banned. Thanks in advance.
It's probably the type of ad, try changing the wording, or try changing the link or the product. Facebook is really picky I hear.
They should leave you a reason on why it was blocked. Normally if there is a problem of your ad, that means there is a violation of their policies. You just have to read them and compare your ads to see what's wrong: https://www.facebook.com/help/adpolicy If they blocked your credit card completely, I guess you have to contact them personally and sort that out.
