Ars Technica: Facebook revamps political-ad rules after discovering Russian ad buys

Ars Technica: Facebook revamps political-ad rules after discovering Russian ad buys. “Two weeks ago, Facebook admitted that a ‘shadowy Russian company’ spent $100,000 on political ads targeting US Facebook users during the 2016 election campaign. At the time, Facebook turned in information about these ad buys to special counsel Robert Mueller, who is investigating Russian interference in the election. Today, Facebook announced that it would also be turning the information over to Congressional investigators. And Mark Zuckerberg announced that Facebook would be stepping up its efforts to prevent foreign election interference in the future.”
