Freedom of speech on HN is subject to the site guidelines, which are at https://news.ycombinator.com/newsguidelines.html. That's for much the same reason that freedom of fire is limited in national parks. If you want to comment here, you need to follow the rules the same as other users do, so please review them.
The HN guidelines aren't a blacklist in which anything not listed counts as fair game. It would be foolish to try to make such a list, plus how tedious—and it would only invite trolls to drive trucks through loopholes. Instead, you need to read them more as a sketch of a certain intention, and then take that intention to heart. Doing that is what makes a good HN commenter, not conforming to a contract adversarially.
HN is a spirit-of-the-law, not a letter-of-the-law kind of place. See https://news.ycombinator.com/item?id=7606756 from 5 years ago.
