Yes, I find LLM-written posts valueless because I can already talk to a LLM any time I want (and get the same info). It's not these commenters are the Queen of Sheba bearing a priceless gift of LLM slop. That stuff's pretty cheap.

Copy+pasted LLM output is actually far worse than prompting an LLM myself, because it hides an important detail: the prompt. Maybe the prompter asked their question wrong, or is trolling ("only output wrong answers!"). I don't know how the blob of text they placed on my screen was generated, and have to take them at their word.
