Interesting, do you have a source on that. I would like to see the agreement researchers have to agree to to use fb data. I'm guessing this includes private profile information not public? Or is it a platform level EULA or something like that?

I wonder how FB views public scraping. Shades of webcrawlers.

NY Time article "The technique had been developed at Cambridge University’s Psychometrics Center. The center declined to work with Cambridge Analytica, but Aleksandr Kogan, a Russian-American psychology professor at the university, was willing.

Dr. Kogan built his own app and in June 2014 began harvesting data for Cambridge Analytica."
