What are the allegations against Cambridge Analytica?
The data analytics firm used personal information harvested from more than 50 million Facebook profiles without permission to build a system that could target US voters with personalised political advertisements based on their psychological profile, according to Christopher Wylie, a former Cambridge Analytica contractor who helped build the algorithm. Employees of Cambridge Analytica, including the suspended CEO Alexander Nix, were also filmed boasting of using manufactured sex scandals, fake news and dirty tricks to swing elections around the world.
How is Facebook involved in the scandal?
The social media company has received a number of warnings about its data security policies in recent years and had known about the Cambridge Analytica data breach since 2015, but only suspended the firm and the Cambridge university researcher who harvested user data from Facebook earlier this month. A former Facebook manager has warned that hundreds of millions of users are likely to have had their private information used by private companies in the same way. On Sunday, Facebook ran adverts in several major UK and US newspapers apologising for the data breach, and said it was investigating other applications that had access to large amounts of user data.
