Anyone who receives such a communication should immediately print out a copy of this thread and go to your local police station and make a report. If enough people do this, they can at least have a press conference notifying the community of the problem.
Ironically, I'm not part of social media for these exact reasons. I have no social media accounts and don't engage in such, however they were still able to find me due to my brother. The fact that they found my name, number & associated me with him as his emergency contact seems more than just a "random dialing" because there are only a few places where that information is given to, ie the er, hospitals, schools.. just goes to show you our information isn't safe anywhere. I have read that they are going through thousands of calls a day off of databases that get traded with numbers and info. Also filed a report, the police seemed more amused that concerned
At 4:30pm a man called saying he had a female member in my family that had been in an accident, soundling like he was a peramedic, and that the number he was given to call as emergancy contact for her was my number. When I questioned why he called me (as the number was a company phone and there is no owner), he then used foul language. I immedately hung up and called 911 to give them this phone number.
