After rejecting the idea that false or misleading news reports on Facebook influenced the outcome of the presidential election, Mark Zuckerberg says the social network is now doubling down on efforts to root out such content.

In a post late Friday, the Facebook CEO outlined his plans to depend on automation, users, and third parties to detect false content. "We do not want to be arbiters of truth ourselves, but instead rely on our community and trusted third parties," he wrote.

As a tech-first company, the social network says it's ramping up its automation efforts to proactively detect spam before users flag it. That means learning what signals suspicious content to a reader so its systems can detect those posts first.

"There are many respected fact-checking organizations, and while we have reached out to some, we plan to learn from many more," he wrote. But the social network can't rely on robots alone: Facebook says it will also improve its process for reporting false news stories, making it easier for users to do so. And once a story has been flagged, Zuckerberg says, warning labels will signal to users that the validity of the story is questionable.

Finally, Zuckerberg says some fake news sources use advertising to make money off clickbait headlines. To combat these financial incentives, the company will be "disrupting the economics" of its ads policies. Last week, Facebook officially banned fake news websites from its ad network.
