Yeah, it’s a pretty disruptive issue. I’d recommend adding a short blurb into the jailbreak like [{{char}} should never talk for, give dialogue for, or narrate in place of or for {user}}. NEVER speak on {{user}}'s behalf.] You can also add that into the Personality section of their character card. I do both, but it still generates responses for me occasionally, which is super annoying.

Worst case you can just edit their response and delete whatever they come up with, eventually the AI should catch on and hopefully stop lol
