I've done this on multiple occasions, e.g.: <https://news.ycombinator.com/item?id=36191005>
As I commented above, HN operates through indirect and oblique means. Ultimately it is is a social site managed through culture. And the way that this culture is expressed and communicated is largely through various communications --- the site FAQ and guidelines, dang's very, very, very many moderation comments. Searching for his comments with "please" is a good way to find those, though you can simply browse his comment history:
- "please" by dang: <https://hn.algolia.com/?dateRange=pastYear&page=0&prefix=tru...>
- dang's comment history: <https://news.ycombinator.com/threads?id=dang>
Yes, it means that people's feelings get hurt. I started off here (a dozen years ago) feeling somewhat the outsider. I've come to understand and appreciate the site. It's maintained both operation and quality for some sixteen years, which is an amazing run. If you go back through history, say, a decade ago, quality and topicality of both posts and discussions are remarkably stable: <https://news.ycombinator.com/front?day=2013-08-14>.
If you do have further concerns, raise them with dang via email: <hn@ycombinator.com> He does respond, he's quite patient, might take a day or two for a more complex issue, but it will happen.
And yes, it's slow, inefficient, and lossy. But, again as the site's history shows, it mostly just works, and changing that would be a glaring case of Chesterton's Fence: <https://hn.algolia.com/?q=chesterton%27s+fence>.
