Neither do I. There’s no technical way it can be happening without it being easily spotted, not to mention how many would have to conspire.

However I am still waiting for a comprehensive explanation for how it is actually happening.

There there are many ways to correlate people and their interests, but I wonder how deep it goes. Basic geolocation and public interaction metadata: Sure. But I’ve also heard people believe that it ought to be possible to spot closeness via Wifi and Bluetooth.

This is such a culturally relevant topic that there must be some serious knowledge about it somewhere.

As for my own tests, I’ve made it a point to mention that I’m considering spending money on a well advertised-for product that I haven’t yet searched for online every time this topic comes up. No ads so far. In the next phase I’ll progressively tell more people to start looking it up.
