Reddit isn't nearly as valuable in shaping the public conversation and narratives as it used to be.

So the person in charge of bots and shills who kept the dozens of posts on all those bigs subs being pumped up daily, which then gave people something to engage with, has moved on and nobody was ever in a place to replace it.

Its the same way that if someone like B-Volleyball stopped posting on KIA1, the place would quickly be a literal ghosttown instead of having its decently high engagement.
