I had the same problem with Facebook. My account has been locked, I never provided ID before, and I most certainly will not now. My only remaining task was to delete the account anyway.
What is the gold standard In dealing with these requests?
Does anyone know what happens if you send in fake id? I have heard of people's accounts getting hijacked with fake passport scans. Is Facebook really able to authenticate IDs?
Facebook does the same, which is annoying as the account I setup and disabled 10 years ago can't be shut down without giving them real PII.
The only sane response to FB would be a Kramer-esque “you know who I am dammit!”
On the other hand, I would be a upset if a service I used deleted my account without first making quite sure it was me.
