Anything I post here is always in my own voice - even when I use an LLM. 95% of the times grammar/spelling is fixed, it's because my brain lapsed while typing, not because I don't know the grammar well and am using LLM to shape my voice.

I would wager that this use case is much more prevalent than ones where the LLM changed the comment significantly enough to change one's voice.

I never copy/paste from an LLM into HN. Everything is typed by myself (and I never "manually" copy LLM content). I don't have any automatic tools for inserting LLM content here.[1]

Always, always, always keep in mind that you don't notice these positive use cases, because they are not noticeable by design. So the problematic "clearly LLM" comments you see may well be a small minority of LLM-assisted comments. Don't punish the (majority) "good" folks to limit the few "bad" ones.

Lastly, I often wish we had a rule for not calling out others' comments as "AI slop" or the like.[2] It just leads to pointless debates on whether an LLM was used and distracts far more than the comment under question. I'm sure plenty of 100% human written comments have been labeled as LLM generated.

[1] The dictation one is a slight exception, and I use it only occasionally when health issues arise.

[2] Probably OK for submissions, but not comments.
