An anonymous reader quotes a report from VICE News: Reddit says it has identified and removed hundreds of Russian propaganda accounts, a few days after reports revealed that Russian trolls were active on the platform during the 2016 U.S. presidential election. In a post Monday, Reddit co-founder Steve Huffman said his site operators had been investigating for awhile and had found a few hundred accounts suspected to be of Russian origin or linked to known sources of Russian propaganda. "Of course, every account we find expands our search a little more," he said, also claiming the "vast majority" of the suspicious accounts were banned back in 2015-2016. An even bigger challenge was the problem of "indirect propaganda," where content produced by accounts now known to be Russian trolls was enthusiastically shared by Trump supporters on subreddits such as r/The_Donald. Reddit's investigation followed a report from The Daily Beast, based on leaked internal data from Kremlin-backed troll farm the Internet Research Agency, that confirmed Russian trolls were active on the site, as well as Tumblr, in their mission to spread disinformation, divide Americans and disrupt U.S. politics. The Washington Post reports that congressional investigators looking into the Russian issue intend to question Reddit and Tumblr over their involvement.
