it seems everyone in this thread is focusing on the wrong issue; the problem was not that "sign-in procedures are too lax", it's that these individuals have access, period - or that the system exists in the first place.
People understand that. I think Flock needs to be dismantled but I'm also a bit shocked (as much as one can be these days) that the login procedures are just a username and password from anywhere. Netflix has stronger access controls.
