Facebook used an automated process to accept app updates, so no-one at the firm may have seen the new policy which revealed the app could sell data obtained from the social media network. In the first version of the app, which was reviewed by Facebook, it said users' data would 'never be used for commercial purposes'. Kogan was hired by CA to build a personality test app called 'thisismydigitallife', which accessed the Facebook profiles of 280,000 Americans with their consent. In the document sent to Facebook, Kogan's company, Global Science Research, asked users for permission to collection information, including likes, status updates and similar data from Facebook friends. He also revealed tens of thousands of other apps may be mining social media for personal data to be sold on.
