Jack is a teacher and he uses Facebook to keep an eye on his at-risk students in case they post suicidal thoughts online. Now Facebook is questioning whether he is a real person or not. Leo says Facebook's new policy requires users to use the same name as is on their ID. This is to prevent bogus accounts from being created, or from identities being stolen. It's likely someone complained to Facebook that Jack wasn't using his right name, even though there's a very good reason not to. Jack could Google student names and then look at their Facebook page without logging in, though. If they've posted publicly, anyone will be able to see it.
