A fake porn video claiming to show Hillary Clinton engaged in a sex act has been traced back to a Reddit account linked to Russia.

The content-sharing platform has confirmed that the “Rubinjer” account that was responsible for posting the content belongs to Russia’s Internet Research Agency.

According to NBC, “Rubinjer” is the Russia-linked agency’s most popular account. It received almost 100,000 upvotes before being shut down by Reddit.

The Internet Research Agency, or IRA, is described as a “troll farm” and has become known for deploying an army of users and bots to post divisive political content during the 2016 presidential election. The troll farm has been connected to both Vladimir Putin and Russian spy agencies.

The offending GIF was posted to Reddit in 2016 and the video to pornographic streaming platform Pornhub, where it has been viewed more than 250,000 times, according to NBC.

The post in question – titled “This is How Hillary gets black votes” – linked to an animated GIF of the fake porn video on Reddit.

The same sex tape was posted at least five times to PornHub under the name “Leaked Hillary Clinton’s Hotel Sex Tape with Black Guy.”

The video was viewed more than 250,000 on PornHub.

Speaking on Russian TV last October, former IRA employee Alan Baskaev claimed the fake video had been created by the Russian agency’s “troll farm.”

On Tuesday, however, the video was finally credibly linked to the troll farm account when Reddit released usernames tied to the Russia-linked agency.

The controversial video shows a blonde older woman having sex with a black man, in what appears to be a hotel room.

Rubinjer was the only account to push the content out on several platforms, both as animated GIFs and full videos.

Reddit is the fourth most popular website in the United States, according to web analysis firm Alexa.

The site is home to one of the largest and most popular Donald Trump fan communities on the web – r/The_Donald.

The forum was even used by Trump to host a Q&A during his presidential campaign.

The fake sex tape was posted by Rubinjer to the r/The_Donald community page during the 2016 presidential campaign.
