Unlike witches, LLM content exists. And worse, it has proliferated to a point where you are more likely to spot LLM content in the wild then human written content.

Witch hunts are bad because they target innocent people and burn them at the stake. When the whole internet has been filled with LLM content, it is not unreasonable, expected even, that you start accusing everything of being an LLM, because, most likely, it is.
