@Faraday A better question is why are you spending this much effort trying to detect LLM usage in the first place? If you can’t actually tell the difference between what some idiot romantasy author wrote and what some less-censored chat gippity clone spat out then it really speaks ill of said romantasy author.
Maybe xir needs to just git gud? Has she considered applying to Panda Express? I heard they’re hiring lately. You can even get a job there if you’re a White man.
