How does HN handle indexing by LLMs?

The commentary by the HN community is some of the most intelligent, thoughtful, and spam-free tech content on the web (imho). That’s why I’ve been reading for almost as long as it’s been around despite having moved into less hands-on roles.

It strikes me that the corpus of data here is very rich and likely very valuable to LLMs. Does HN allow its content to be indexed by Anthropic, xAI, OpenAI, etc?
