The results were published on June 7th. JAMA Internal Medicine..
“If you want to rectify the’infodemic’, eliminating bots on social media is the first step you need to do,” Ayers said. “Unlike the controversial strategy of censoring real people, silencing automated propaganda is something everyone can and should support.”
