Company says it removed more than 50,000 accounts and reported them to investigators, marking latest upward revision of figures
Twitter has admitted that more than 50,000 Russia-linked accounts used its service to post automated material about the 2016 US election – a far greater number than previously disclosed.
Announcing the discovery in a post to its website late on Friday, the company said the posts had reached at least 677,775 Americans, all of whom would be receiving a warning by email.
Strictly defined, a Twitter bot is any automated account on the social network. That can be something as simple as automatically tweeting links to news articles – most of the Guardian’s social media accounts are technically Twitter bots, for instance – to complex interactions like automatically generating Emoji-based art or automatically replying to climate change deniers with scientific evidence.
