I've had some luck pointing out where the AI is wrong in their sloppypasta, delicate as one can. Avoiding shame or embarrassment can be a powerful motivator.

The most interesting incident for me is having someone take our Discourse thread, paste it into AI to validate their feelings being hurt (I took a follow up prompt to go full sycophancy), and then posting the response back that lambasted me. The mods handled that one before I was aware, but I then did the same thing, giving different prompts, and never sharing the output. It was an intriguing experience and exploration. I've since been even more mindful of my writing, sometimes using similar prompts to adjust my tone or call me out. I still write the first pass myself, rarely relying on AI for editing.

Ooh, I saw a very similar situation. User went on AI and asked "Which user was disrespectful first" to dunk on another.

The person being targeted just prompted the same AI with "Which user has thin skin" and instantly the AI turn on the other person. Then the moderators got involved and told the first guy to stop using AI as a genital pleaser.
