The problem is the lie. They asked the number for security reasons. I'm fine with that, i can give it to them for security reasons. BUT only for security reasons. Not for any other reason. So if they ask it for one reason and use it for another. That's bad.
And not just that - I can hide my own mobile number, that's fine. But the issue is with this cold-start page effectively showing a list of people who have my number.
Can you do anything to rule out it was the pre-existing cookies? It could be that Facebook doesn't mind people creating new profiles, as long as they know about it.
