Moderation of threads has been done the same way for years on HN. The guidelines have been in place and essentially the same for many years, and it's been the same people upholding them for a long time too.
Please read and observe the guidelines, particularly these ones:
Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.
Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.
When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."
Please don't fulminate. Please don't sneer, including at the rest of the community.
Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith.
Eschew flamebait. Avoid generic tangents. Omit internet tropes.
Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.
Please don't use Hacker News for political or ideological battle. It tramples curiosity.
This is not why your comment was flagged.
