Relevant excerpt from your own wiki guideline:

"Do not rely too much on your own judgment. [...] if you are an expert user of LLMs and you tag 10 pages as being AI-generated, you've probably falsely accused one editor."

Never accuse people of LLM writing based on short comments, your false positive rate is invariably going to be way too high to be acceptable given the very limited material.

It's just not worth it: Even if you correctly accuse 9/10 times, you are being toxic to that false positive case for basically no gain.
