In these figures, we can observe that tweets reporting unverified rumours are more widely spread; the percentages of unverified tweets range from 30.73% of the retweets in Ebola/Essien, to 100% of the retweets in the Putin missing story.
Retweets of inaccurate reports are especially remarkable in the Ferguson unrest (26.78%) and the Ebola/Essien hoax (69.27%). Retweets of accurate tweets can only be observed in Prince/Toronto (23.36%), Germanwings plane crash
(33.32%), Ottawa shootings (35.76%), and the Sydney siege (26.64%). Table 3 shows the percentages of retweets of each type of tweet (unverified, accurate, inaccurate) for each of the events. (Source)
