That's pretty extreme: I don't think random bloggers that host comment sections need to be laying out terms of service. Instead, they can handle things as they come up, and the community is small enough, and stakes are low enough, that this is fine.
HN is bigger than a blog, but it's still small enough that it can be fully moderated with 1-2 people, and I think similar tradeoffs apply here.
