You're not using some kind of mobile router/dongle thing for network access are you?

Otherwise all that's left is you - how you type, click & otherwise use FB.

Edit: and the 1st thing the goddamn site shows me is a pop-up begging for a Like :\

I'm not, in fact I'm using a different ISP entirely. You really think my behavior patterns are uniquely identifiable at FB's scale? I can't imagine how many other users must have similar typing/clicking/resting/etc. patterns.

Interestingly, my comment's getting down-voted without refutation. C'mon, let's talk :)

Anyway, no, I don't know if FB can do that at scale.

What I do know is that sites, especially complex ones like FB, like to track user interaction to evaluate UX (hover targets, click targets, time it takes to find call-out etc).

If I were a data science type at FB, and knew FB was collecting that stuff, I think I'd like to find out what other questions I could answer with it.

Or more banal - did you use your laptop as a wifi endpoint and connect your phone & WhatsApp to it?

Wow, that makes a lot of sense.

Welcome to the post-privacy era, I guess.
