But there was a clear skew in who shared links from the 91 sites the researchers had manually coded as “junk news” (based on breaching at least three of five quality standards including “professionalism”, “bias” and “credibility”). “The Trump Support group consumes the highest volume of junk news sources on Twitter, and spreads more junk news sources, than all the other groups put together. This pattern is repeated on Facebook, where the Hard Conservatives group consumed the highest proportion of junk news.”
One thing the study did not find is evidence of substantial amounts of Russian news sources being shared. “The political conversations on social media exclude a Russian audience group,” the researchers concluded.
