Did you just forget about the mobilization drive Russia had in 2022, where they grabbed young men off streets and from their houses?
It was very unpopular, lead to people fleeing the country, and was pushed out of the public eye as soon as they figured out how to forcefully volunteer people instead.
I believe they're just comments pulled in from google+ threads that mention the video in question, based on the logic that all comments on the video should be grouped. The problem is that people don't actually comment on videos on google+, they just share content.
See, I don't see that as a user. The bad comments sections used to be full of bad puns and arguments, but now they're just smaller and full of contentless "watch this" mentions. On channels where the comments used to be good, they are now rare and inaccurate.
