Facebook says 3,000 Russia-linked ads appeared during US elections, pledges to hire 1,000 people to fight fake news

Facebook has said it will hire more than 1,000 people to thwart deceptive ads crafted to knock elections off course.

The announcement came as the leading social network turned over to Congress some 3,000 Russia-linked ads that appeared to use hot-button issues to turn people against one another ahead of last year’s US election.

“Today we are delivering those ads to congressional investigators,” Facebook vice president of global policy Joel Kaplan said in an online post.

“Many appear to amplify racial and social divisions.”

The ads appeared to be linked to a Russian entity known as the Internet Research Agency, and violated Facebook policies because they came from inauthentic accounts, according to Kaplan.

“Aggressive steps” by Facebook will include hiring more than 1,000 people to bolster its global ads review teams in the coming year, Kaplan said.

Facebook also planned to ramp up investment in machine learning to identify and take down ads violating the social network’s policies.

“Enforcement is never perfect, but we will get better at finding and removing improper ads,” Kaplan said.

Facebook will require those interested in running ads related to US elections to confirm businesses or organizations they represent.

Facebook chief executive Mark Zuckerberg last month announced a crackdown on efforts to use the leading social network to meddle with elections.

Zuckerberg outlined a series of steps that would help prevent the manipulation of the social network, including more transparency on political ads appearing on Facebook.

Facebook last month agreed to hand over information about the ads from the Internet Research Agency to special counsel Robert Mueller’s investigation of the 2016 election.

An internal Facebook review showed that Russia-linked fake accounts were used to buy ads aimed at exacerbating political clashes ahead of and following the 2016 US presidential election.

Some 470 accounts spent a total of approximately $100,000 between June 2015 to May 2017 on ads that touted fake or misleading news or drove traffic to pages with such messages, a Facebook official said.
