Indeed, and since the author has clarified what they meant by "40%", I've put the post back on the front page. Another relevant factor is they seem not to speak English as a primary language, and I think we can make allowances for such people to use LLMs to polish their writing.

Regarding your other suggestion: it's been the case ever since HN started 18 years ago that moderators/modcomments don't have any special designation. This is due to our preference for simple design and an aversion to seeming separate from the community. We trust that people will work it out and that has always worked well here.
