What happened

On June 8, protesters in Bulgaria took to the streets against the country's planned adoption of the euro. Kostadin Kostadinov, a nationalist politician known for his opposition to the currency switch, was among the crowd. Within days, a video began spreading online that showed him tripping while trying to climb over a fence during the demonstration.

The clip was never real footage. It had been built from a single still photo taken at the protest, then animated into motion with an AI video generator. The only sign of its origin was a watermark from a tool called Haliuo AI, and even that had been partly cropped out before the video made the rounds. Multiple accounts reposted it, and it collected more than a million views before the manipulation became widely known.

The math here is brutal. One photograph and a generation tool were enough to manufacture a moment that never happened, attach it to a real event, and put it in front of an audience the size of a small country's population. Nobody needed to hack an account or fabricate a quote. They needed a picture that already existed and a few minutes with the right software.

What makes this incident worse than a simple prank is the target. Kostadinov is a sitting political figure, and the video landed during an active protest tied to a genuinely contentious policy debate. A fabricated pratfall is designed to humiliate, and humiliation aimed at a politician during a live political fight is not neutral content. It is a manipulation of the public record at the exact moment people were forming opinions about him and the movement he represents.

The watermark should have been the safety net, and it barely held. A partial crop was all it took to strip away the one built-in signal that the clip wasn't genuine. Platforms that reposted it did nothing to verify the footage before it reached seven figures of views, and no one has identified who made it or why.
