The tweet that sparked the largest controversy over the 2016 presidential campaign last week was sent by Hillary Clinton’s campaign manager, who called for a “fire sign” in the middle of a speech.
The Twitter account @RealHillaryClinton had already deleted the tweet but not before its image was tweeted more than 30,000 times.
Clinton’s Twitter account was then suspended.
But it’s not the first time Twitter has been accused of censoring speech.
In August 2016, the social media platform was fined $1.8m for its handling of a user’s tweet that threatened violence against police officers in Dallas.
Twitter had earlier faced similar controversy over its handling last month of a tweet from the campaign of US presidential candidate Donald Trump, which included an image of a burning US flag.
