P.S.: That said, I can imagine this technique being used in an arguably-moral way, putting poisonous data on pages that scrapers and LLMs have not been permitted to use, to trigger nonsensical behavior down the line. Much like how poison works in nature, protecting the animal from ingestion by anything that ignores the warning-colors.
