Thank you, Facebook, and goodbye

I have never used facebook (except years ago under a false name for reasons connected with my job). Recently I wished to join one specialist group and created a new profile under my real name. No problems getting in, other than:

• FB insists on my address being Ruislip, Slough.
• It refuses to recognise the "high" school I went to (it requires selection from a list, the school is not in the list and it won't let me add it)
• It persistently changed the dates of my various jobs forcing me to re-enter them several times to get it right.

But today I am told for "security reasons" I must send them a photo of myself and the account is disabled.

I have done absolutely nothing with this account other than connect to the group I mentioned above. They have not told me what the security reasons are. They have no way of knowing if the new photo I sent is really of me because I only uploaded one other selfie before and both could be of someone else.  I registered my mobile with them but they have not bothered to use it to help to verify my account.

I don't need this frustration.
