I just keep coming back to someone finding Mickey (and some of the other missing young girls - and I am not limiting area, I think there could be a traveler of some kind - ) and then stalking via FB. I keep mine pretty private, but, I just ot done working with a relative to get her girls (late teens) more private. They never gave it a thought. And I know I can come across as a paranoid Aunty/Mom/Friend, but hey I am a Websleuther and I KNOW things.
The whole location being added to statuses and the "checking in" wherever people go makes me very nervous. Why would ANYONE want people to know where they are at? Aren't people even a little paranoid instinctively?
