I had the same issue but in instagram, not for personal use, but few years ago I made few startups, and every time I register the company I create few social accounts, all works well except instagram for some reason, always get flagged and asked to take a selfie with a book or something.. and even after providing that selfie I still get perma banned! I tried to call support, like how you would expect from any company let alone a multi billion one, only to find out that there’s actually no support in anywhere in fecebook wise! And the only way you can get something fixed is through a secret syndicate-like community where you should know someone who knows someone to talk to some person there to fix your issue. Long story short, never bothered with that shitty company again, good riddance.
