Twitter Inc has announced it would label or remove misinformation aiming to undermine confidence in the US election, including posts claiming victory before results have been certified or inciting unlawful conduct to prevent a peaceful transfer of power.
Twitter said in a blog post it was updating its rules to recognize the changes in how people will vote in the Nov. 3 election and try to protect against voter suppression and misleading content on its platform.
The widespread use of mail ballots in the US election due to the coronavirus pandemic will likely cause significant delays in tallying results, which some experts fear could allow misinformation to gain traction.
US President Donald Trump has repeatedly claimed, without evidence, that voting by mail is susceptible to large-scale fraud.
A Twitter spokesman said whether content had specific falsehoods or could cause greater harm would determine if it would be removed, or labeled and have its reach reduced.
Social media companies have long been under pressure to combat misinformation after U.S. intelligence agencies determined Russia used their platforms to meddle in the 2016 presidential election, allegations Moscow has denied.
