Since the value of HN is its community, we have to regulate the comments carefully. The main tool for doing that is https://news.ycombinator.com/newsguidelines.html. Not to do so would cause HN to suffer the default fate of internet communities, which tend eventually to become burnt-out husks of their former selves. The idea here is to stave that off for as long as we can: https://hn.algolia.com/?dateRange=all&page=0&prefix=false&qu....
That's why we keep asking you to follow the site guidelines. It's not just because your individual comments get better when you do that. It's also because the feedback loops involved (the effects of comment quality on the community) are large and existential for HN.
