Volume of data suggests trusted partnership with Aleksandr Kogan, says analyst
Before Facebook suspended Aleksandr Kogan from its platform for the data harvesting “scam” at the centre of the unfolding Cambridge Analytica scandal, the social media company enjoyed a close enough relationship with the researcher that it provided him with an anonymised, aggregate dataset of 57bn Facebook friendships.
Facebook provided the dataset of “every friendship formed in 2011 in every country in the world at the national aggregate level” to Kogan’s University of Cambridge laboratory for a study on international friendships published in Personality and Individual Differences in 2015. Two Facebook employees were named as co-authors of the study, alongside researchers from Cambridge, Harvard and the University of California, Berkeley. Kogan was publishing under the name Aleksandr Spectre at the time.
