The bad guy already got all the info.
People post on facebook under their real names.
They accept GPS tracking and all kinds of stuff in order to be able to install some moronic app on their phone.
They post pictures of their house, their family, the kids, their dog, their cats, their vacation online.
Their car, their brand new watch and everything else they can think of.
They make sure everybody knows when they leave the house, and where they go. They check in on restaurants, bars, cafees, gyms and tell everyone about it.
