I recently, for no particular reason, have been watching some of the top videos on YT over a couple of months. I noticed many (most?) of the top comments are made by accounts that on a closer look are promoting or even selling what must be some kind of scam or MLM. Would be fair to call them submarine comments. Several of them were even verbatim duplicates of other comments on the same video. I got the feeling that a lot of this is automated, and not by the people supposed to be running the platform. Just open up the YT front page in a clean unpersonalized session and go into those Minecraft/Fortnite/whatever that tend to end up high in the rankings and you’ll probably see what I mean.
