Most people don't know about Facebook's invasive data practices, study finds

Three quarters of Facebook users are unaware that the social network lists their personal interests and traits for advertisers, according to new research. A study published by Pew Research Center revealed the scale of Facebook users' ignorance when it comes to how the tech giant uses their data to make money. Facebook consistently claims that it is transparent in its data collection practices, making it possible for people to find out how its algorithm categorises their interests via the'Your ad preferences' page. But the research suggests that most users are unaware of this. In a survey of 963 US adults, 74 per cent said they did not know Facebook maintained lists of their interests and 51 per cent said they are not comforable with Facebook compiling this information.
