Facebook rolled out a chatbot to advise employees on how to answer questions about its controversies

Consultancy firm Cambridge Analytica had offices in London, New York, Washington, as well as Brazil and Malaysia. The company boasted it can'find your voters and move them to action' through data-driven campaigns and a team that includes data scientists and behavioural psychologists. In 2013, Cambridge professor Aleksandr Kogan used his app, This Is Your Digital Life, to ask 270,000 Facebook users questions about their personalities. By answering them, the users granted Kogan access to not only their profiles but to those of their friends. He subsequently sold that information to Cambridge Analytica for $51million.
