Cambridge Analytica was looking for people who were American Facebook users. It offered to pay them to download and use a personality quiz app on Facebook called thisisyourdigitallife.
About 270,000 people installed the app in return for $1 to $2 per download. The app “scraped” information from their Facebook profiles as well as detailed information from their friends’ profiles. Facebook then provided all this data to the makers of the app, who in turn turned it over to Cambridge Analytica.

Queste azioni smuovono solo qualche indeciso, alla fine e' tutta la campagna e chi presenti (capito Renzi e Clinton?) che fa la differenza
