I’m going to close this topic as we don’t allow discussion of account specific restrictions here, as described in the rules. Contacting support is the best way to get more info.
I will add this though: Your page may be quarantined if your account behavior is similar to instances of other accounts that have participated in malicious activity in the past. No automated system is perfect though. Your page is placed into a queue to be reviewed by our team. If you aren’t doing anything suspicious and we don’t find any issues, then the status will likely be removed within a few days. Unfortunately we do not share the specifics of how this detection works because it will enable malicious actors to circumvent detection.
The best way to avoid any issues in the future is to have a long-standing account that you publish to without any issues. Once you’re recognized by our system then it’s highly unlikely you account will be marked for review.
Hope that helps
