I bought a new SIM to have a new phone number, create a new email, registered a new Apple ID from a different IP, got to the step where I have to pay for the dev account and all of the cards I used got me an error. Banks saying Apple did not even try charging them.
What do you think is flagged here, your name, or banking info? Name pattern matching seems a bit unlikely/incompetent since sometimes people got identical names. Same phone? Maybe the IMEI part is flagged. Have you tried a residential IP?
Just in case you are on some greater shit-list (maybe by accident, by someone else's doing), I would take a moment to make sure you know how to behave when searched, got nothing too incriminating at home/your car (i.e. illegal drugs), your drives/backups are encrypted and your master password isn't pinned on a post-it. If your existence is bound to local data, make sure to have remote backups anticipating your devices getting confiscated.
