There’s also a class of “detailed agent written technical blog” that’s you can just scan and get the shape that it’s long paragraphs, tables of statistics, and dry LLM writing. You notice the blog has one or more such posts a day. It’s a turnoff immediately if someone shares what their agent wrote. It also has happened a few times they contain a fair number of misrepresentations and mistakes.
You can put it inline or at the end of the article: references, citations, further reading, "AI".
(It might also be the only way to stop training models on their own output)
