The nutters on Facebook were right
The social media company has admitted to knowing about data-harvesting practice since 2015
The website Junkee put it like this: "You know that one friend who’s always warning you that Facebook is harvesting all your data to subtly manipulate your thoughts? As it turns out, they were kind of right."
Facebook, it has transpired, published targeted content based on user profiles that users did not know were shared with third parties. This content was used by the Donald Trump campaign and by pro-Brexit lobbyists to sway voters in their favour. Apparently it succeeded.
Here’s how it worked, according to Junkee. In 2014, Aleksandr Kogan made an app called thisisyourdigitallife, which 270,000 people downloaded. If they had read the fine print, they would have realised they had given him access to data they shared on Facebook.
Kogan went further. He gained access to information from their friends. In the end, he had the data of 50m people at his fingertips. He sold this to Cambridge Analytica, a firm that specialises in manipulating people based on their data.
Cambridge Analytica was hired by Trump and the Brexiteers, among others.
We would have been none the wiser had former employee Christopher Wylie not blown the whistle. He told The Guardian: "It is a propaganda machine. If you can control all of the streams of information around your opponent, you can influence how they perceive that battle space, and you can influence how they’re going to behave and react."
Both firms are now under pressure over abuse of privacy. Coming soon is a Channel 4 exposé in which Cambridge Analytica’s Alexander Nix is said by The Guardian "to talk unguardedly about the company’s practices".
Reporters posing as clients are said to have filmed meetings with the company.
Facebook has admitted to knowing about this data-harvesting practice since 2015. And your Facebook friends have warned you about this for longer. You know, those posts from nutters you ignore because you know better?
