Re: ‘People You May Know’ helped Facebook grow exponentially
#112In the early days, Facebook logged into user's email accounts and stole contact information without users' knowledge or authorization. This was possible because people used the same password for their email and Facebook, a practice common especially back in those days. This is one of their sources for PYMK. In fact Facebook has used this technique very recently too: A security researcher noticed the tech giant was pr…
"Unintentionally uploaded" Because you just happened to accidentally interact with the API in just the right way and downloaded the information to just the right database and deployed a service to production which just happens to access that data... I don't understand how that statement right there isn't literally incriminating evidence. They admitted to uploading the data explicitly, and "unintentional" is a straigh…

Suppose A has contacts B and C. If A chooses to share contacts with Facebook, and Facebook suggests B and C to A, I can see why you'd say that's not an invasion of privacy. If Facebook suggests A to C, that's arguably an invasion of privacy. If Facebook suggests B and C to each other, that's unarguably an invasion of privacy.
> If Facebook suggests B and C to each other, that's unarguably an invasion of privacy. How so? Alice tells me she knows Bob and Charlie. I mention Charlie to Bob - completely normal human thing to do. Maybe I think they're in the same circle but I've forgotten exactly why or how I found that out - completely normal human memory behaviour. Where's the invasion of privacy?
In both cases.
Yours is understandable and forgivable. Charlie's privacy may have been violated, but it was a simple mistake.
But suppose you say to Alice, "Tell me all the people you know. I'll tell you which ones I know too." If you then write down that list and systematically start telling them about each other and that they have Alice as a mutual friend, then you're a privacy-invading jerk, and Alice was wrong to trust you.

This is not a dystopian fantasy; it's exactly how intelligence agencies map out terrorist groups' and foreign militaries' structures online. Israel is supposedly particularly good at this kind of analysis, but I'm sure other countries are doing it.
And all the "males of fighting age"

#117> But monthly was a better indicator, because someone consistently on the service for a full month was likely there to stay. That is not what a monthly active user is, even at Facebook. A MAU logs in once per month, a DAU logs in once per day.
Is there a difference between an "active user" and just a "user"?

The geo thing is really happening.
Which is one big reason why the only sensible way to use Facebook on mobile is to delete the app and use only a browser, while keeping your location sensors turned off.

I also have the theory that they are using WiFi names / AP MAC addresses as well. If you happen to be connected to the same private WiFi network, you probably know each other.
Facebook has a patent for using dust and scratches on photos to track which camera they came from. But they claime(d) not to be using WiFi or Geolocation for the PYMK feature - https://gizmodo.com/facebook-knows-how-to-track-you-using-th...
