Yes, generated comments aren't allowed here and that has been the case since before GPTs. HN is for humans.

We haven't added a specific rule to the guidelines about it (https://news.ycombinator.com/newsguidelines.html) but we may end up having to.

What's tricky is that accusing other commenters of being bots/AIs is, at the same time, a new twist on the "you're a shill/astroturfer/troll/bot/spy" etc. swipe that internet users love to hurl at each other, and which we do have a guideline against (for good reason).

Between those two rules (or quasi-rules) there's a lot of room to get things wrong and I'm sorry I misread the above case!
