Yeah I personally don't give it much thought. I write what I want to write, reread what I wrote, make sure it makes sense and briefly check for errors, then submit (at least as that's how I write HN comments, other venues may require more or less process).

Admittedly sometimes I'll pass my text through an LLM to check for obvious mistakes I may have missed. But the text itself was mine.

If that makes someone think I'm a bot, then maybe it's OK that we didn't engage anyway.
