Twitter Inc suspended more than one million accounts a day in recent months to reduce the flow of misinformation on the platform, the Washington Post reported.
Twitter and other social media platforms such as Facebook Inc have been under scrutiny by U.S. lawmakers and international regulators for doing too little to prevent the spread of false content.
The social media platform has more than doubled its crackdown rate since late last year, the Post said, when testimony from Twitter, Facebook and Google revealed startling new data showing many more millions of Americans were exposed to fake news than previously thought.
Russia-linked fake accounts are believed to have fired off false tweets in an effort to sway the 2016 US presidential vote.
In recent years Twitter, which has some 336 million active users, has faced sharp criticism for allegedly not doing enough to control the proliferation of bots and trolls created to spread disinformation.
The new offensive against such accounts represents something of an ideological shift in the tech company; it had long abstained from policing potential abuses of the platform in the name of free speech.
Del Harvey, Twitter's vice president for trust and safety, told the Post that the company is changing "how we think about balancing free expression versus the potential for free expression to chill someone else's speech." "Free expression doesn't really mean much if people don't feel safe," Harvey told the paper.
