I watched through one of his videos. If memory serves, it was him wandering around Mariupol right after the Russians finished turning it into rubble. He happened upon a man who told him how wonderful the Russians were. All this in what were supposedly the ashes of his hometown. It was the most transparently staged bullshit I've ever seen. Probably a Russian soldier with a few scripted lines.

I think a lot of the folks on Lemmygrad consume a lot of Russian state media and media that draws from Russian state media. Lancaster is regularly featured on Russian state media, so it makes sense that they would be passing around his content.
