“In the 2010s, personal data belonging to millions of Facebook users was collected without their consent by British consulting firm Cambridge Analytica, predominantly to be used for political advertising. The data was collected through an app called "This Is Your Digital Life", developed by data scientist Aleksandr Kogan and his company Global Science Research in 2013. The app consisted of a series of questions to build psychological profiles on users, and collected the personal data of the users’ Facebook friends via Facebook's Open Graph platform. The app harvested the data of up to 87 million Facebook profiles. […] Aleksandr Kogan, a data scientist at the University of Cambridge, was hired by Cambridge Analytica, an offshoot of SCL Group, to develop an app called "This Is Your Digital Life" (sometimes stylized as "thisisyourdigitallife"). Cambridge Analytica then arranged an informed consent process for research in which several hundred thousand Facebook users would agree to complete a survey for payment that was only for academic use. However, Facebook allowed this app not only to collect personal information from survey respondents but also from respondents’ Facebook friends. In this way, Cambridge Analytica acquired data from millions of Facebook users.” https://en.wikipedia.org/wiki/Facebook%E2%80%93Cambridge_Analytica_data_scandal https://en.wikipedia.org/wiki/Facebook%E2%80%93Cambridge_Ana...
