I’m pretty sure there’s something even more perverse happening maybe IP tracking. Maybe phone location tracking. Like when I search for stuff on Google here at home on my phone that stuff appears on my work Google (where I have never actually logged in to Google with any account). It maybe a server side user profile tracking system that we haven’t seen before. Instead of tracking a user via IP, you look at a location… Then you look at what people are searching for in that location and you develop a profile for that particular hardware ID.
