Facebook data harvesting and the hunt for the 'friend' who betrayed me Michael McGowan

Two weeks ago I logged into good old Facebook dot com to discover I was one of the 311,127 Australians – and one of about 87 million people worldwide – who had their personal data harvested by Cambridge Analytica sometime around 2013-15. I was a small and unwitting cog in a vast, beguiling narrative of unfurling geopolitical upheaval encompassing the Trump presidency, Russian interference and Brexit. Here's what Facebook told me. I was not one of the 270,000-odd people who signed up to the now infamous This is Your Digital Life survey app but one of my friends was. As a result, Facebook "probably" shared my public profile, page likes, my date of birth and the city I lived in.
