I guess you might be too busy tone policing, as per usual: https://news.ycombinator.com/item?id=20993139
As the site guidelines explain, the way to react to a bad comment on HN is not to feed it by replying, but rather to flag it and (in egregious cases) to email us at firstname.lastname@example.org. Posting more comments complaining about lack of moderation doesn't help, for the same reason: we might not see it. In fact we probably won't, if we didn't see the original post in the first place. Making your complaint as sarcastic and cruel as you can doesn't add to its visibility.
Would you please review the site guidelines and follow them? They're written the way they are because, to avoid HN deteriorating further, users need to help preserve the site. Letting moderators know about egregious comments (in ways that work—flagging or emailing) is one way the guidelines ask you to do that. Not being snarky or calling names is another.
You and your alt account do not make up "the community". Since I make comments related to the articles and discussions then I am way more a part of the HN community than you are. Anyway, I invite you and your alt account to respond to the content of what I write in order to have a constructive conversation.
