I don't use FB personally, but I needed access to Business Manager for some client work so I created an account using my work email and tried to sign up for BM. They immediately locked the account, asked for a copy of my ID, and then permanently banned that account after I provided it. I have no idea why, there's no mechanism for appeal, and I can't even submit a request to have the image of my ID removed because that form is gated behind the account.

Their "KYC" system has no problem with the 10-year-old alt that I created in college using a fake name which has never done anything but manage some ancient meme pages, though...
