Triggering the Senate’s new interest is a trove of documents first reported by the Daily Beast last week. It found at least 21 accounts on Tumblr had ties to the Internet Research Agency, a Kremlin troll farm that was the focus of an indictment last month by special counsel Robert S. Mueller III.
A spokeswoman for the chairman of the Senate Intelligence Committee, Richard Burr (R-N.C.), did not immediately respond on Monday. But the panel’s top Democrat, Sen. Mark R. Warner of Virginia, said the latest reports highlight the need for other tech companies to study their own platforms for potential misuse.
Warner, for one, expressed reservations with Reddit back in September 2017, fearing it may have helped amplify Russian propaganda online.
Otherwise, Russia is not Reddit’s only recent trouble. The site, which allows its users to post under cover of anonymity, has fielded criticism for enabling everything from white supremacist content to fake videos of celebrities having sex — and most recently, it served as a breeding ground for conspiracy theories about the mass shooting in Parkland, Fla.
