Bots spread fake news on Twitter.And real news. “We find evidence that
social bots playa disproportionate role inspreading and repeatingmisinformation.” (source).
“Contrary to conventionalwisdom, robotsaccelerated the spread oftrue and false news at thesame rate, implying thatfalse news spreads morethan the truth becausehumans, not robots, aremore likely to spread it”(source)
Propagation of fake news: Nodes and links represent Twitter accounts andretweets of the claim, respectively. Node size indicates account influence,measured by the number of times an account is retweeted. Node colorrepresents bot score, from blue (likely human) to red (likely bot).
