I think NKRFZ had a video about a weird genre of pro-war fiction that is published en mass in Russia and promoted quite alot, but which does not really sell.
I suspect the commenter is either ignorant or just decided to roll in all the terrible sequels...
But I imagine that abusing SEO to ensure search results don't show people the results they actually want to see (or maybe "need to see", but that's quite the can of worms to open) is a legitimate tactic in any propaganda machine.
