Oft repeated lies become the truth
Repeat a lie often enough and it becomes the truth”, is a law of propaganda often attributed to the Nazi Joseph Goebbels. The 2016 election showed how critically timed social media news can damage fatally the candidacy of electoral candidates with little or no remedy in law. (It is not illegal to spread rumours in a foreign country).
Yet tech majors can help. With browser embedded plugins, they can analyze and scrutinize the sentiment, the polarity, the word association of a web page. With the added advantage of IP address lookups, the social media can be a fair place for news just like credit bureaus are fair places for credit ratings.
Unless you like Russian Hackers for the people, of the people, by the people.
