Fun tidbit: in an attempt to remove 2FA so that we can login, I signed up a new account and associated her phone number with the new account in hope of removing it from the previous account. The method did infact remove the number, then we got a 2FA form on her account with a grand total of ZERO choice (an empty selection list on the popup). Note that her facebook profile was disabled to me before I try this, so I don't think this was the reason for the suspension. And another thing that I still couldn't explain to this day: on the day of her losing access to the account, she received a garbage SMS which looks like Chinese, but it wasn't -- I asked a Chinese speaker, they said it read garbage. After copying it and changing encoding (from/to UTF-8/UTF-16 something, I can't remember the detail), turned out it was a 2FA sms text from FB. I have no idea how her phone turned it into garbage text.
