It will also be “significantly limiting” recommendations to those channels, YouTube said in a statement.
The company said the channels are affiliated with recent sanctions, and that it has restricted access to RT and other channels in Ukraine in response to a request from that country’s government.
As the crisis in Ukraine intensifies, social media companies have been scrambling to rein in misinformation and Russian state propaganda.
The move by YouTube follows the ban announced Friday by Meta on Russian state media’s ability to run ads and monetize them on Meta’s platform. Meta’s head of security policy, Nathaniel Gleicher, said on Twitter Saturday that the company will continue putting labels on additional Russian state media posts.
Meta global affairs president Nick Clegg said Russia ordered the company to “stop the independent fact-checking and labelling” of four Russian outlets.
“We refused,” Clegg said in a statement. “Ordinary Russians are using our apps to express themselves and organize for action. We want them to continue to make their voices heard, share what’s happening, and organize.”
