Facebook will disclose the demographic groups that Russia-linked ads targeted during the 2016 election, the Wall Street Journal reported. Sheryl Sandberg, Facebook’s chief operating officer, said the company would also hand over to congressional investigators non-paid posts created by the fake accounts. However, a social media researcher said Facebook took down thousands of Russia-linked posts last week, preventing further open-source research on the impact of the fake accounts, according to the Post. That researcher’s previous work had suggested that the Russia-linked accounts’ non-paid content had reached tens of millions of Americans. CNN reported the Russian influence campaign extended across platforms to YouTube, Instagram and Pokemon Go.
