With your anecdote I suddenly have a flashback of my own golden shitposter who posted 5 post a day and was just two copied paragraphs + 1 image of a Marvel Superhero.
I stopped commenting and following him when it was apparent he was just making it as placeholder posts for bots and I looked at his prfile now Rep 67 although his SP is almost 3k as all the SP he got from the bots but no engagement.

He wasn't looking at building something he just wanted to selfvote and cash out.
