Facebook Abstainers could be labeled Suspicious
As examples they use Norwegian shooter Anders Breivik, who used myspace instead of facebook (or as they put it, "largely invisible on the web", haha @ myspace), and the newer Aurora shooter who used adultfriendfinder instead of facebook. So being social on any other website isn't good enough, it has to be specifically facebook that people are using.
While it is already established that sites like facebook and google+ are no good for political activists, abuse survivors, and people in the witness protection program; abuse survivors will have to take a back seat while more and more insane articles like this come out.
There seems to be an insanity bubble around older people which has arrived after the initial facebook boom that brought in the youth, where they see facebook as a necessary utility; instead of a trendy website that will have passed in a few years.
