Same thing here. Created a brand new email that had never been used before. Signed up for market place. Got banned after a few hours and blocked from marketplace unless I uploaded an ID or a selfie to prove my age. I just didn’t do anything and eventually the approval came in and now I can use marketplace. It seems they just ask for your id as a courtesy—I bet they have a copy of my drivers license already—they just didn’t want to disclose it lol. .
