I've also noticed that very obviously LLM-generated comments are called out, and the community tends to agree, but those that have any plausible deniability are given far too much leniency, and people will over-index on the guidelines to give them the benefit of the doubt.
I don't think a captcha is the solution, as it'll degrade conversation by an OOM though.
The one thing I like about this place is that it's well moderated and you have shared opposing view points engaging (mostly) respectfully.
My personal and political views couldn't be further from most HN users (I'm both a Conservative _and_ a practicing Christian), yet I appreciate taking part in various discussion. I enjoy reading about point of views that directly challenge mine.
Let's keep HN respectful and accessible.
If your view is that we should conserve western values and institutions and walk in the footsteps of Christ, ultimately that's not too far from universal human values that many people do in fact agree with.
The devil is in the details, of course.
