Err, we did!
Regular readers will have seen my post last year which talked about the dangers of over sharing. It described pretty much exactly what’s happened with Cambridge Analytica, on a massive scale.
I’m not going to go into detail on what they did – there’s a lot of news coverage you can check out – but basically an individual’s details and those of their friends were harvested and used for targeted advertising with the aim of swaying voting in the US election in 2016. Other elections may also have been influenced in this way.
This is a great example of why you should regularly check your privacy settings on social media, and be careful what information you decide to share.
