I think dang's intention here is to prohibit undisclosed comments posted by either bots or lazy humans, not topical, attributed comments that were generated by models and posted as part of a good-faith discussion by actual users.
Can't speak for dang, obviously, but that's the rule I'd make in his shoes.
dang has made it clear that all generated comments and articles are off topic. Hacker News is for human discussion, and AI generated content undermines that.
A blanket prohibition may be futile but it's anything but pointless.
Once Hacker News becomes nothing but bots posting stories written by bots for other bots to comment on - which is the inevitable end point of a permissive attitude towards this stuff - what even is the fucking point to any of this? SEO juice?
Just a heads up in case you didn't know, but generated comments are not allowed on HN: https://news.ycombinator.com/item?id=45077654
