It’s happen when facebook detect that you are using a fake account.
First, Facebook ask to verify our identity.
Second, We should enter the captcha
Third, Facebook will show us some photos of people we’re connected to on facebook. There 5 photos challenge to identify.
Fourth, If we succeed with the challenge we can login to our account, but if we not succeed, we should try again after one hour.
Actually, it is very hard for us to pass the photo challenge, because it is not photo profile, but it is photo that we are tagged.
What about if you have more than 1,000 friends in one week, and you know only litle of them?
It happen to me today. Is there other way to get our account back?
Thank for your respon.
