Can you be manipulated? That is the question posed by the Netflix documentary "The Great Hack". It considers the Donald Trump 2016 election and the surprise Brexit vote in Britain. Cambridge Analytica was hired to provide voter data which it acquired from social media. They collected data points on millions of voters. They wanted to know likes, dislikes, Google searches, et cetera to profile undecided voters which they bombarded with biased political ads.
Take care when you connect to the Internet World Wide Web (a.k.a World Wide Waste of Time).
