While Facebook, Twitter, and Google have all testified before Congress about the ways trolls from the Russian Internet Research Agency abused their platforms to create political chaos during the 2016 election, Tumblr has remained remarkably silent on the matter. It added that it is now working to “protect Tumblr in the future.”

During the investigation, the company notified law enforcement, terminated the IRA-linked accounts and deleted all of their original posts. Microblogging platform Tumblr, perhaps best known for its memes and fan communities, is sending emails to users who interacted with accounts linked to the Internet Research Agency (IRA), a propaganda group tied to the Russian government that spread political messages on social media designed to disrupt the 2016 presidential election. Tumblr also said it will begin keeping a public record of usernames linked to the IRA and that it will “be monitoring Tumblr for signs of state-sponsored disinformation campaigns.” It also encouraged users to keep an eye out for propagandists, be skeptical of what they’re reading and call out people who are spreading misinformation.
Tumblr shuts down 84 accounts linked to the Internet Research Agency.
