Americans who may have been served posts from Russia's Internet Research Agency on Facebook
Facebook told Congress the troll farm's 120 pages published more than 80,000 posts from January 2015 to August 2017. About 29 million people were served those posts directly; after sharing, the estimate rose to roughly 126 million. Facebook's own testimony warned that many of them may never have actually seen the posts, which made up about 1 of every 23,000 posts on the site.
