I always wonder where people find this obscure content.
ETA. OK, it's now clear where such things are found. Downstream of ops like this one:

That channel was *entirely* Russia/Ukraine/Israel content for the last few days (out of nowhere). All featured Russia's favorite American war analysts. I clicked on one video featuring a disturbing person and all of the comments (and there were quite a few) were Russia - "rah rah" comments. I didn't see any comments against the position made by the "expert". (Who was, by the way, claiming that we'd all be dead now if the UK had granted Ukraine permission to hit military targets inside Russia with Storm Shadow cruise missiles.)
The profile had an name in some southeast Asian language (not enough for me to recognize), but I suspect Vietnamese. The profile picture matched that identity. The description text and all of the earlier cooking videos were in Turkish.
I never thought I'd get to see one of those real Russian disinfo YT channels in the wild, but there it was.
