The only context I didn't mention is I set up an ad campaign the week prior to boost a post for the startup in question. I suspect that this is what triggered the ID verification a few days later, which resulted in an "appeal denied" email. I can only guess. But I did receive a confirmation email about my avatar being taken down due to their policy; and the appeal message mentions "misrepresenting my identity".
