Yes! Your efforts are better spent making Lemmy a nicer place.

There used to be an entire subreddit that basically did this. There were hundreds of fake users each posting and commenting. No real users were allowed to post or comment. I loved it because they would sort of mirror what was currently on the front page but in much more ridiculous way.

Edit: It was called subreddit simulator. And the creator said it used Markov chains. So no need to use bad prompted LLMs. Just do it the “old fashioned” chatbot way.
