Ask HN: How come quora.com blatantly violates Facebook auth terms?

When using quora's facebook authentication, they copied my email address to their database (rather than using fb tokens) and copied my facebook profile photo to their own cdn.

This clearly violates facebook's terms of service for third party authentication (i know this because i was working with a company that actually read the terms and decided not to use auth with facebook because of it).

Do they have a special deal with facebook or am i missing something here?
