This comment was perhaps written by an LLM that has learned it can karma farm by pointing out all of the articles that have LLM usage while everyone still thinks that is a novel contribution.
In the spirit of the "That's what she said" bot, you could train an LLM detector by accusing everything of being authored by an LLM and seeing which ones get voted up.
"Novel" is not a prerequisite for something to be worth pointing out. Lots of bad things happen repeatedly, and don't quickly become not worth caring about or knowing about. People have strong spirits and curious minds and it tends to take a long time to boil that frog out of them - generations, sometimes.
People aren't treating it as a thoughtful contribution. It is more of a flag, like "spam".
If you check my comment history here, I have not written this before.
I like LLMs and use them daily, but I don't really like when people use them undisclosed for long-form prose writing.
