Nearly half of the Twitter accounts spreading messages on the social media platform about the coronavirus pandemic are likely bots, researchers at Carnegie Mellon University said Wednesday.
Researchers culled through more than 200 million tweets discussing the virus since January and found that about 45% were sent by accounts that behave more like computerized robots than humans.
It is too early to say conclusively which individuals or groups are behind the bot accounts, but researchers said the tweets appeared aimed at sowing division in America.
“We do know that it looks like it’s a propaganda machine, and it definitely matches the Russian and Chinese playbooks, but it would take a tremendous amount of resources to substantiate that,” said Kathleen Carley, a professor of computer science at Carnegie Mellon University who is conducting a study into bot-generated coronavirus activity on Twitter that has yet to be published.
Researchers identified more than 100 false narratives about COVID-19 that are proliferating on Twitter by accounts controlled by bots.
Among the misinformation disseminated by bot accounts: tweeted conspiracy theories about hospitals being filled with mannequins or tweets that connected the spread of the coronavirus to 5G wireless towers, a notion that is patently untrue.
Such bogus ideas on the Internet have caused real-world harm. In England, dozens of wireless towers have been set on fire in acts officials believe have been fueled by false conspiracy theories linking the rollout of 5G technology to the coronavirus.
“We’re seeing up to two times as much bot activity as we’d predicted based on previous natural disasters, crises and elections,” Carley said.
Using a so-called bot-hunter tool, researchers flagged accounts that tweet more than is humanly possible or claim to be in multiple countries within a few hours’ period. Researchers say they examine a Twitter account’s followers, frequency of tweeting and how often the user is mentioned on the platform in determining whether the tweeter is a bot account…
