Re: Facebook's shadow profile.
in my case of FB stalking i’ll privilege the IP cross-matching hypothesis
i created a burner FB profile for Tinder. new pix, slightly different name (same age (: ). my phone, a near death wifi-only Android never left home. FB app had never been activated on that phone before. i never surfed anywhere while logged into this FB on my browser. never friended anyone from it.
yet within days i had tons of friend suggestions for people i did know, but barely. somebody’s cousin or mother for example.
Actually, LikedIn shows the exact same behaviour. I created a new profile, pretty much blank. No CV, new contact details, different name, "joined" another company.
It took less than a day before it started to suggest, very focused, to connect to old colleagues.
