A campaign using the hashtag #HollywoodagainstZelenskyy has spread doctored videos of celebrities urging European leaders to pressure Ukraine into accepting a peace deal with Russia. Fact-checkers found these videos on platforms like X and TikTok, where they were shared by accounts with no credibility. The videos falsely present personalized messages from celebrities, including Nikki Blonsky and Jon Seda, and manipulate footage to push anti-Ukrainian narratives. Researchers link this campaign to a broader influence operation known as 'Matryoshka', which uses fake accounts to disseminate disinformation.
