Facebook to verify identities, require labels for political ads

Facebook announced Friday it will require political ads on its platform to state who is paying for the message and would verify the identity of the payer, in a bid to curb outside election interference.

The social network, which is under fire for enabling manipulation of its platform in the 2016 election, said the new policy would require any messages for candidates or public issues to include the label "political ad" with the name of the person or entity paying for it.

Facebook chief Mark Zuckerberg said the change will mean "we will hire thousands of more people" to get the new system in place ahead of US midterm elections in November.

"We're starting this in the US and expanding to the rest of the world in the coming months," Zuckerberg said on his Facebook page.

"These steps by themselves won't stop all people trying to game the system. But they will make it a lot harder for anyone to do what the Russians did during the 2016 election and use fake accounts and pages to run ads."

A separate Facebook statement said the changes would help improve transparency and accountability of the network around political campaigns.

"We believe that when you visit a page or see an ad on Facebook, it should be clear who it's coming from," the statement said.

To get authorized by Facebook, "advertisers will need to confirm their identity and location," the statement said.

Facebook made the announcement as Zuckerberg prepared to appear before Congress next week to answer questions about the harvesting of personal data on 87 million users by Cambridge Analytica, a British political consultancy working for Donald Trump's presidential campaign.

The move also comes amid concerns that Russian-sponsored entities delivered Facebook ads designed to create discord and confusion ahead of the election and that firms like Cambridge Analytica created messages based on psychographic profiles gleaned from the platform to influence voters.

Separately, Facebook chief operating officer Sheryl Sandberg offered fresh apologies to users for failing to do enough on privacy and data protection.

"We know that we did not do enough to protect people's data," Sandberg told National Public Radio. "I'm really sorry for that. Mark is really sorry for that, and what we're doing now is taking really firm action."

Sandberg said Facebook first became aware in 2015 that Cambridge Analytica had obtained user data from a researcher who put up a poll on the social network.

"When we received word that this researcher gave the data to Cambridge Analytica, they assured us it was deleted," she said.
