They do real time privacy checking. They wrote about it in their engineering blog.
So for a query like "All Oracle employees who like sailboats and tennis", they check to see that the person has shared each of these facts with you, and only shows up if everything checks out. It's possible for you to be friends with someone who is an Oracle employee but they have only shared their employer information with a select group of people which doesn't include you. So they would not show up in that query you make.
- lostnet 14y agoI was actually referring to the danger of allowing specific profile criteria in advertising campaigns not in public queries. The advertiser will presumably never see the actual profiles of the fb users, but they will know too much about the visitor(s) arriving from that Ad. The post I replied to implied allowing "creepy" levels of targeting for Ads was not such a risk.
- onedev 14y agoRight, that's their whole business, as is Google's. They developed a platform that takes their valuable data and allows for targeted advertising, and they sell advertising on that platform. The advertiser never sees the actual profile page or even know that they showed an ad to a particular user. Only the platform and the algorithms know this. "Creepy" levels of targeting is pretty subjective. I don't think its creepy because the other side is essentially oblivious to who they're advertising to. I'd rather see no ads at all, but if I had to put up with ads, I'd rather see ads that advertise topics that I'm interested in rather than something that's completely irrelevant to me. Of course, that's just my opinion.
