“The evidence we've collected shows a highly engaged and far-reaching Tumblr propaganda-op targeting mostly teenage and twenty-something African Americans. This appears to have been part of an ongoing campaign since early 2015,” Albright, research director of the Tow Center for Digital Journalism at Columbia University, told BuzzFeed.

In many instances, Tumblr accounts featured their corresponding Twitter accounts, which were revealed by the company to be linked to the Internet Research Agency, a Russian “troll farm” that pushed misinformation on Facebook and Twitter around the time of the election.

Many of the accounts featured names like 4mysquad, Blacktolive and Bleepthepolice, and pushed both messages of racial empowerment and incendiary content that sparked outrage.

4mysquad, for example, galvanized outrage when it posted a video of a police officer assaulting a black teenager, falsely claiming that the officer worked for the New York Police Department.

BuzzFeed reports that the 4mysquad accrued hundreds of thousands of followers.

The accounts also pushed anti-Clinton rhetoric during the election, including a video from the 1990s in which Clinton called black gang members "superpredators."

4mysquad also posted a photo of Clinton hugging former Sen. Robert Byrd (D-W.Va.), who had been a member of the KKK in the 1940s, with the text, “Hillary Clinton embracing KKK leader Robert Byrd, where is the media on this?”

Congressional investigators have focused their probe of Russian influence on internet platforms on social media giants Facebook, Twitter and Google, however, the Tumblr accounts suggest that influence efforts were likely not limited to the platforms of these three companies.
