Also you can broadcast two profiles at the same time if you use different devices. The Tom profile might say when he last broadcast, but he probably switched it to password mode first so no one could view him. I use something called CamNotifiier and have the Tom profile on there, but I have never had an alert he is broadcasting. If he wasn't in password mode I would have received an alert.
Can you share the full user name for that other profile? What’s the background there? I haven’t heard about it before. Maybe he has a second account with different regional settings.
