ad networks don't offer targeting that is anywhere near that level of sophistication. demographic profiling is really coarse and not very accurate. they're probably just using a history of other requests they've gotten for that fingerprint, and trying a few coarse predictions based on that.
I also don't know about "sites" offering "PII" back to ad networks based on a fingerprint match. but I could be wrong about that or maybe people are using a more expansive definition of PII.

- kevin_thibedeau 7y agoIt isn't just apps. Data aggregators are inferring personal information from retail purchases. That all feeds into your profile.
- kevin_thibedeau 7y agoThe profiling exposed at the top level is coarse. I guarantee you that companies the likes of Acxiom are tracking every woman's periods and they've been doing it for decades. That PII gets squirreled away into their database and feeds into whatever genericised category it is useful for. Sign the right NDA and you get all the goods.
