You're absolutely correct!
actually maybe not ⸻ a lot of people take pride in (re)posting AI generated content, their only human contribution being "I asked $AI".
Consider also (but maybe I'm projecting) that people do drive-by shitposts all the time, so they would post their slop grenade (I will use that term from now on lmao) and never see what the responses are. I've done that for years on various platforms (minus the slop) and I honestly don't know how well-known or well-received my shitposts are, I check some metrics every once in a while and numbers go up so it's not all bad I suppose.
