Facebook warned on Monday that it could offer no assurance that social media was on balance good for democracy, but the company said it was trying what it could to stop alleged meddling in elections by Russia or anyone else.
The sharing of false or misleading headlines on social media has become a global issue, after accusations that Russia tried to influence votes in the United States, Britain and France. Moscow denies the allegations.
