San Francisco, Sep 22 (IANS): Facebook is bracing for tough measures to restrict content in case the November elections in the US descend into chaos or violent protests, according to a report in the Financial Times on Tuesday.

The plans were revealed by Facebook's head of global affairs, Nick Clegg, in an interview to the newspaper.

"There are some break-glass options available to us if there really is an extremely chaotic and, worse still, violent set of circumstances," Clegg was quoted as saying.

Facebook is under pressure to help maintain the integrity of the elections as it has faced criticism for failing to contain the spread of disinformation and hate speech on the platform.

It was even accused of failing to prevent attempts to create divisions in American society through disinformation campaigns by foreign players during the 2016 presidential election.

The stakes appear to be even higher this time with reports of similar attempts to influence the US presidential elections by groups operating from Russia, China and Iran.

Facebook CEO Mark Zuckerberg earlier this month announced additional steps it is taking to help secure the integrity of the US elections by encouraging voting, connecting people to authoritative information, and reducing the risks of post-election confusion.

These include measures to attach an informational label to content that seeks to delegitimise the outcome of the election or discuss the legitimacy of voting methods, for example, by claiming that lawful methods of voting will lead to fraud.
