I was never in 4chan, and it's only very recently I've found out that it isn't just a Nazi forum. Like, I legitimately thought it was just some far right wing forum. Like truth social is to Twitter, 4chan is to forums. I had no idea it had other content.
It's also entirely useless for marketing or for selling anything, because it is infested with the kind of content that infests a place when there are no content restrictions, and will likely damage a brand more than it helps.
Also I'm pretty sure everyone there sees everyone else there the way you'd see vermin, as the literal dregs of society. Hard to astroturf when nobody reading has a thimble's worth of respect for you or what you say. Very self-aware kind of humor. I don't know how well astroturfing would work in 4chan for the major subset of the audience(The ones with a minimum of common sense).

I genuinely think that's the only thing that kept 4chan around and pure for this long. It's too chaotic for enshittification as no business want to touch it, and their not interested in growth.
The astroturfing and botting is constant and prevalent but everyone is suspicious and hostile over everything that it's an instant shit slinging argument where no one is convinced. Hell, I would guess that half the fighting is bots with opposing agendas.
