> In Jimmy’s case, though, I simply cannot fathom how Instagram made this connection... and so I’ve written Jimmy’s case off as a mystery that will remain unsolved Is it really that mysterious? The connection could have been made in the other direction. For example, Jimmy could have had the author's email address in his contact list and allowed access to his contact list to some web site? Jimmy could have searched for the authors name on Instagram (not sure - I'm not a user) at some point?
