Q: Is there a policy for AI bots on HN? If not, what are your thoughts on making one?

Background: I was wondering if there are ways to automate certain common types of interactions on HN. Like dropping a comment with an archive.org link for paywalled stories or unfurling a twitter thread etc. Also, I am sure a lot of bots already exist for promoting some content etc.

Suggestion: IMHO, an official way to mark accounts as bots could be beneficial to the community and then penalizing those that are masquerading as real people.
