I setup a new Microsoft account and tried to buy minecraft. Maybe I mistyped a digit, maybe I just got flagged for being an unusual user agent, but I got the account stuck in purgatory indefinitely, along with my credit card number (no starting a new account).

Having gotten flagged that way, there’s no way to buy it anymore; other payment methods also fail due to the flag.

Support took weeks and multiple escalations to figure it out, by which point I had migrated the family server to minetest (which has so many qol improvements that the kids were thrilled to change).
