Facebook CEO Mark Zuckerberg will have to personally answer to federal regulators under an agreement to settle a privacy case with the Federal Trade Commission that includes a $5 billion penalty for the giant social media company, the agency announced Wednesday. Separately, Facebook will pay $100 million to settle a case with the Securities and Exchange Commission for making misleading disclosures about the risk that users' data would be misused, the SEC said.
Under the FTC agreement, Zuckerberg will be required to submit quarterly compliance reports directly to the federal regulators and to Facebook's board of directors. If the Facebook co-founder or "designated compliance officers" violate the agreement, they could be subject to civil and criminal penalties, the FTC said.
"There's no way that the CEO can bury his head in the sand," James Kohm, head of the FTC's enforcement unit, told NPR. "There's no ostrich defense."
According to FTC investigators, Facebook violated the terms of its 2011 settlement with the agency, in which it promised to protect user data from broad sharing with third-party apps. The company also committed new violations, they said.
Kohm described two major incidents in which Facebook effectively lied to users.
First, the company solicited phone numbers, saying they were being collected to verify users' identity if a password needed to be reset. Millions of people trusted the company, and then Facebook took those phone numbers and used them not just for security, but also for advertising purposes, the FTC said.
Also, according to regulators, the company conducted facial recognition tracking on 60 million users without proper consent. Facebook must notify users who were affected and offer to delete the data collected.
In a blog post Wednesday, Facebook said the FTC agreement "is not only about regulators, it's about rebuilding trust with people. ...
"We have heard that words and apologies are not enough and that we need to show action. By resolving both the SEC and the FTC investigations, we hope to close this chapter and turn our focus and resources toward the future," the company said.
In a separate post, Zuckerberg wrote: "We have a responsibility to protect people's privacy. We already work hard to live up to this responsibility, but now we're going to set a completely new standard for our industry."
In an earnings call earlier this year, Facebook disclosed it was expected to pay a multibillion-dollar fine to regulators. Following the company's announcement, the stock price jumped. Investors continued to have faith in the business.
Some critics charge the FTC fine is too small, but Kohm said it sends a tough message.
