That is not clear at all, based on another article. [1] Further, Facebook's lawyers told Wylie that the data was illicitly obtained, though now apparently they've changed their approach. [1] 'Kogan was able to throw money at the hard problem of acquiring personal data: he advertised for people who were willing to be paid to take a personality quiz on Amazon’s Mechanical Turk and Qualtrics. At the end of which Kogan’s app, called thisismydigitallife, gave him permission to access their Facebook profiles. And not just theirs, but their friends’ too. On average, each “seeder” – the people who had taken the personality test, around 320,000 in total – unwittingly gave access to at least 160 other people’s profiles, none of whom would have known or had reason to suspect.' --from https://www.theguardian.com/news/2018/mar/17/data-war-whistleblower-christopher-wylie-faceook-nix-bannon-trump https://www.theguardian.com/news/2018/mar/17/data-war-whistl...
