"... we immediately banned Kogan's app from our platform, and demanded that Kogan and Cambridge Analytica formally certify that they had deleted all improperly acquired data. They provided these certifications." How is it at all possible to certify that data has been deleted and no copies were taken..?

This feels strange to those of us from technical spheres, but much of the world works without formal verification of facts. There are in theory severe penalties, both implicit and explicit, that ostensibly act as deterrent to bad actors. This is usually only noteworthy when it fails, but by and large it works. The friction involved if we did not generally accept someone's (signed, notarized, appropriately formalized)…

Including many technical spheres, and particularly including the vast majority of the software world; formal verification exists in software, of course, but is most notable in not being used for most of it. Yet, even without that, there's usually a release process that includes the moral equivalent of a certification—without formal verification or certain knowledge—that the software does what it is supposed to.

Is it clear exactly what 'data' was actually obtained by CA on those millions of people? (I am referring specifically to the millions, not the original subset of 200,000 or so). Is it all public and friends-visible activity? Or it is basics such as name, email, profile photo, etc.? I cannot find so far addressed in the coverage exactly what kind of information CA have had on a per-person basis. If someone can share c…

If I remember correctly, back in the day when the API still existed it would only give access to your friends public information

Yes, sorry, I should have been more specific. But what 'exactly' do they know. Does CA know that each person liked EXAMPLE POST ID #12379 on DATE XX/XX/XXXX and that you also like BRAND1, BRAND2, and that you also posted STATUS UPDATE1 on DATE .... What exactly do they have?

The 2007 and 2013 paragraphs are pretty scary. Your friend takes a personality quiz from a random app developer and then that developer gets access to _your_ personal data. Obviously Zuckerberg doesn't go into detail about what kind of data that was, but if they needed to rein that in in 2014... I imagine it was potentially pretty personal.

I created an app so I could grant myself access to the API with it. It was an embarrassing amount of data on all your friends.

Like what?

The New York Times is reporting that they were also able to collect likes, because this was back when likes could be harvested through the API. Through likes alone, they could supposedly determine race, gender, sexual orientation, and other physical and mental traits/preferences with surprising accuracy.

Here is today's episode of The Daily where they discuss this: https://www.nytimes.com/2018/03/21/podcasts/the-daily/cambri...

Please don't; that just leads to the same discussion over and over, which makes it off topic for HN (https://news.ycombinator.com/item?id=16616988).

There's tons of substance to be discussed here without reaching for the global hash table (https://news.ycombinator.com/item?id=9722096). Fortunately the community has mostly been doing that, but let's not spoil it.
