Philip Howard, who runs the Computational Propaganda Research Project at Oxford, studied the deployment of propaganda bots during voting on Brexit, and the recent American and French presidential elections. Twitter is particularly distorted by its millions of robot accounts; during the French election, it was principally Twitter robots who were trying to make #MacronLeaks into a scandal. Facebook has admitted it was essentially hacked during the American election in November. In Michigan, Mr. Howard notes, “junk news was shared just as widely as professional news in the days leading up to the election.”
