We all know Facebook and google collect peoples data and sell it but I think this is going a bit too far.
"The data was collected through an app called thisisyourdigitallife, built by academic Aleksandr Kogan, separately from his work at Cambridge University. Through his company Global Science Research (GSR), in collaboration with Cambridge Analytica, hundreds of thousands ofusers were paid to take a personality test and agreed to have their data collected for academic use. However, the app also collected the information of the test-takers’ Facebook friends, leading to the accumulation of a data pool tens of millions-strong".
" Cambridge Analytica spent nearly $1m on data collection, which yielded more than 50 million individual profiles that could be matched to electoral rolls. It then used the test results and Facebook data to build an algorithm that could analyse individual Facebook profiles and determine personality traits linked to voting behaviour. The algorithm and database together made a powerful politiacl tool. It allowed a campaign to identify possible swing voters and craft messages more likely to resonate."
