If I'm remembering correctly, dang (the main moderator here) specifically stated that ChatGPT comments are not allowed unless it's obviously stated as such, and even then, only if ChatGPT's response is notable for the discussion.

The component of honesty for me is the social contract that we're interacting in good faith, which for me also implies that you're accurately representing yourself. The implication (and rules) for commenting here is that you're a human writing to another human. To break this basic foundation, even if assumed, is dishonest in my opinion.

I am not sure there's any social media platform that someone could ethically post ChatGPT responses to unless the entire account is clearly labeled as AI.

Your comment brings up the interesting aspect of people who have disabilities and use ChatGPT to assist in their messaging. But that's another conversation.
