WASHINGTON: Facebook Inc received several tongue-lashings during US congressional hearings this week, but the world's largest social network also got an assignment: Figure out how to notify tens of millions of Americans who might have been fed Russian propaganda.
US lawmakers and some tech analysts are pressing the company to identify users who were served about 80,000 posts on Facebook, 120,000 on its Instagram picture-sharing app, and 3,000 ads that the company has traced to alleged Russian operatives, and to inform them.
