Facebook suspends analytics firm

摘要

A WHISTLE-BLOWER says that Cambridge Analytica accessed private information on millions of Facebook users without their permission, and used it to target political advertising. Christopher Wylie says that a privately built app gathered data from around 270,000 Facebook users who completed surveys, but this also gave the app access to data on millions of people who were friends with those users, such as their name, location, age, gender and page likes. This was used to make predictions about personality, he says.
