Twitter Inc. sold data access to the Cambridge University academic who also obtained millions of Facebook Inc. users’ information that was later passed to a political consulting firm without the users’ consent.
Aleksandr Kogan, who created a personality quiz on Facebook to harvest information later used by Cambridge Analytica, established his own commercial enterprise, Global Science Research (GSR). That firm was granted access to large-scale public Twitter data, covering months of posts, for one day in 2015, according to Twitter.
