Exclusive: An in-depth look at Facebook's content police

President Donald Trump and Massachusetts Democratic Senator Elizabeth Warren don’t agree on much — but both have condemned Facebook (FB) for how it polices posts and ads on its site. So have concerned parents, human rights advocates, United Nations investigators, and U.S. House Speaker Nancy Pelosi.

Concerns about misinformation on Facebook reached a fever pitch after the 2016 presidential election, the outcome of which some have attributed to a Russian disinformation campaign on the platform. When revelations surfaced last year that Cambridge Analytica, a consulting firm hired by the Trump campaign, had harvested the data of 50 million Facebook users, distrust of the company worsened.

In an exclusive interview at Facebook’s Menlo Park headquarters with the three executives who oversee content at Facebook, the company responded to its detractors.

The execs — Monika Bickert, Head of Global Policy Management; John DeVine, VP of Global Operations; and Guy Rosen, VP of Integrity — spoke at length about the efforts the company has made to moderate content and mitigate and adjudicate hot-button issues like hate speech, misinformation, and hacking.

With 2.4 billion monthly users spread globally across the company’s four primary platforms — Facebook, Instagram, WhatsApp, and Messenger — it’s no small task.

Zuckerberg and Sandberg are heavily involved with content issues

Just how hands-on are CEO Mark Zuckerberg and COO Sheryl Sandberg when it comes to sensitive content issues at Facebook)? According to top executives at the social media giant, they are “incredibly involved.”

That’s important because with Facebook under fire from regulators over questions on several fronts including possible antitrust violations, freedom of speech, data security, and national security, the focus of the company’s two top executives reflects the social media giant’s priorities and how it responds to myriad criticisms and challenges.

The three executives who spoke to Yahoo Finance describe the process of navigating sensitive content issues as “nuanced” where intelligent and good-intentioned participants often disagree. And they, and others at the company, spoke of Zuckerberg and Sandberg’s stepped-up involvement in that process.

“Any time that we're dealing with something that is close to the line or it's something where it's not really clear how the policies apply or it's something that's particularly important, we will, at the very least, send an email up to Mark and Sheryl so that they know what's going on,” Bickert told me. “Very often, we will end up having a back-and-forth with them about why we're making the decision we're making, and make sure they're OK with it.”
