Similar Social media creepiness happened to me yesterday. 2 of my coworkers popped up as suggested friends on fb despite me never looking them up. One of them I have in the contacts of my phone which I guess could associate data. The other I have never looked info up about online.

I also don't use the stock fb app on facebook, I use metal for android which is just a wrapper for the mobile site. So figured it wouldn't be listening or tracking proximity but I guess that k was wrong.

I don't like adding coworkers on social media like that except in firing cases.
