MrDeKart (Sergey Inyutin) is a Ukrainian Russian-language video blogger and streamer. He gained prominence in the mid-2010s through let's play gaming content. He was born in 1990 in the Ukrainian SSR and lives in Mykolaiv.

MrDeKart's Stance on the War in Ukraine
Following the outbreak of the full-scale invasion, MrDeKart repeatedly addressed the war, the Russian government, state propaganda, and anti-Ukrainian rhetoric. Below are key excerpts from his statements and videos that outline his public position.
Statements Following the Start of the Full-Scale Invasion
At the beginning of the full-scale invasion, MrDeKart was located in his hometown of Mykolaiv. On March 11, 2022, in a video, Sergey described the shelling and his daily reality. He noted that things had grown quieter, but on March 7 there had been intense bombardment:
On the seventh, it was total madness... the bombing went on practically from morning till evening. It was surreal: the moment a bomb exploded, I thought: 'Looks like I can record now,' so I start filming — and another bomb hits... I was running around: trying not to get hit, and making sure it wasn't heard in the recording.
He urged his audience (especially Russian viewers) to follow his Telegram channel and Yandex Zen (where he continued posting videos through 2022) in order to stay in touch should YouTube be banned.
In a YouTube Community post, the creator further described his situation amidst active combat and urged Ukrainian viewers to stay safe.

Criticism of Putin and Russian Politics
On Telegram, Sergey shared a satirical poem mocking Vladimir Putin, branding him a “Botox Napoleon”.
In an April 28, 2025 video titled “INTERNET FREAKS — WHAT HAPPENED TO THEM...”, MrDeKart ridiculed “Pynya” and authoritarian Russian legislation following the introduction of mandatory warnings regarding “LGBT propaganda.”
Pushback Against Ukrainophobic Remarks
In a video response from March 2025, he reacted fiercely to a hostile comment claiming “DeKart is hiding in his pigsty dodging mobilization.” The YouTuber fired back sharply, calling the user a “nonentity with a petty Z-patriot soul” and condemning threats regarding Ukraine being annexed by Russia.
In a video published on April 2, 2025, MrDeKart slammed the anti-Ukrainian user SpidX, who hurled slurs at Ukrainians during a Counter-Strike 2 match. DeKart emphasized that the user was sitting safely in Russia — the country that launched an unprovoked invasion of Ukraine — while mocking Ukrainians. Sergey asked why the individual, while claiming to joke about both sides, never dared make similar remarks about Russians or criticize the so-called “special military operation.”
The dude sits in the country that invaded my homeland, mocks my people, spews disgusting slurs about them, and simultaneously calls me toxic!... Hurling slurs at Ukrainians while living comfortably in your 'great' Russia, that's an entirely different story — over there that's encouraged, isn't it?
Criticism of Russian Z-Patriots
In August 2026, in the video “THE MOST SHAMEFUL CONFLICT! — DeadP47 Reaction”, MrDeKart took aim at Russian streamer Fasolka and other Z-patriots. He strongly criticized combat drone production in the Alabuga Special Economic Zone, ridiculed pro-war figures who flee Russia to avoid consequences, and condemned imperialistic claims targeting Kazakhstan. Sergey also backed the Kazakh authorities' decision to deport Fasolka for provocative misconduct.
Condemnation of Kremlin Propaganda
In September 2026, DeKart released the video “BREAKDOWN OF A MADMAN”, debunking creator Shedshiy, who defended following Kremlin propagandists Vladimir Solovyov, Olga Skabeyeva, Artemy Lebedev, and others on the grounds of “high production value.”
You praised evil for its efficacy... They looted state funds, invested it into a machinery built to dumb down the population — and that suddenly makes society better?
DeKart emphasized the elephant in the room that the commentator attempted to ignore — direct endorsement of the war by Russian state media figures:
How smoothly you dance around the reality that all these characters are actively engaged in continuously justifying the war and championing aggression. And nobody seems to notice the elephant in the room!
He additionally mocked pro-government influencers who attempt to mask their regime collaboration behind “rage-bait” and “post-irony,” labeling such tactics as cynical opportunism and obsequious groveling before authoritarian power.
