The New York Times reports:
One hour after news broke about the school shooting in Florida last week, Twitter accounts suspected of having links to Russia released hundreds of posts taking up the gun control debate. “This is pretty typical for them, to hop on breaking news like this,” said Jonathon Morgan, chief executive of New Knowledge, a company that tracks online disinformation campaigns. “The bots focus on anything that is divisive for Americans. Almost systematically.”
Any news event — no matter how tragic — has become fodder to spread inflammatory messages in what is believed to be a far-reaching Russian disinformation campaign. The disinformation comes in various forms: conspiracy videos on YouTube, fake interest groups on Facebook, and armies of bot accounts that can hijack a topic or discussion on Twitter.
When the Russian bots jumped on the hashtag #Parklandshooting — initially created to spread news of the shooting — they quickly stoked tensions. Exploiting the issue of mental illness in the gun control debate, they propagated the notion that Nikolas Cruz, the suspected gunman, was a mentally ill “lone killer.” They also claimed that he had searched for Arabic phrases on Google before the shooting. Simultaneously, the bots started other hashtags, like #ar15, for the semiautomatic rifle used in the shooting, and #NRA.
