Ask HN: Why does Uber need ID to DELETE account?

A friend of mine was asked to send a copy of her government-issued ID to confirm her account. It freaked her out too much -- they kept on creepily insisting she immediately send a copy -- so she wanted to close the account. Now they won't let her close her account either, and demand to see a copy of her ID. Her number, email, CC info hasn't changed, so why in EARTH does Uber want someone's ID to DELETE their account? So now they've locked her out of her own account (they still have her CC info, and other highly personal info, mind), and won't take any action until she shows her ID.

If someone from Uber's lurking here, I wouldn't mind help with the support. It is getting ridiculous
