> This info is anonymized and barring extreme measures you can’t be identified individually in a data set. It’s sold with very specific usage rights, and for advertising uses a cpm (cost per thousand) fee. You can’t ever buy the data set, but just the ability to target users who exist in it.

I attended a presentation some years back from TMobiles marketing team.

According to the speaker, when you visit their homepage they pull up complete financial records on you, including how much your home mortgage is, if any, and use that to customize what products you see promoted first.

As far as I’m aware (and I’d hope I’m up to date here) that’s only possible if you’ve logged in to your account, so they’d have your name/etc.

Matching a cookie to individual names is not instantaneous and would be very expensive for someone at t mobile’s scale to do every time a session started.

Some b2b companies do something similar where they can match your ip to a list of known corporate ips to find where you work in real-time, but that’s pretty expensive.
