    Unfortunately this doesn't have any technical detail about what data is shared with which party during real-time ad bidding, so it's hard to judge how much of a privacy risk it is. I haven't found a good resource for that yet. The kind of investigation I'd like to see is for someone to sign up to sell ads or serve ads and see what info they can get.

    (Some people think targeted ads are inherently a privacy risk but I don't see it that way.)

      It's a pretty big privacy risk, especially in the sense that the entire system relies on building an incredibly detailed profile of you. Anybody with enough money and your contact information can target you with advertising and build their own detailed profile of you. The article, while not going into too many specifics on its own, does link to other articles, papers, and direct sources of information to gather specifics if you want them. The IEEE paper in particular is really good.

      Even if ads aren't an inherent privacy risk, they are invasive at best. The entire system is setup to get you to buy things you don't necessarily want or need, even from the very beginning. The fact that Chrome is moving towards limiting adblocker capabilities (to the surprise of nobody) means we're getting closer to a future where we are constantly bombarded by ads unless we pay to opt out, ala the Black Mirror episode.

        Yes, that's a good paper, showing how an advertiser could extract information that Facebook or Google didn't intend to reveal if the audience is targeted enough. I wonder if Facebook and Google have done anything in response?
