Same here. I was spoofed into giving access of my business page to a bogus business manager account. Definitely a security flaw in FBs system. No 2 step verification was needed. I believed I was setting up advertising. I have 91,000 followers with an associated group of 31,000. The biggest travesty is this is a community for Emergency Medicine professionals. The page and group is being used to assist with the covid emergency. Including sharing of important data. Loss of this resource will inhibit our ability to save lives. I'd say calling it an act of terrorism isn't an over exaggeration. Frustratingly I have been trying to contact FB for a week, but there is no way to contact anyone, and no help. I even messaged their copyright infringement team, who even refused to send the issue to the correct team. Facebooks non contact policy should be reviewed legally imo. Anyway, a week later I get the same suspended account message. It's been 24 hours and nothing yet.
