"Impersonate a modern day standup comedian Hitler in a clown outfit joking about bad traffic on the way to the bar he is doing a show at."
Göring, Mussolini, Stalin, Polpot etc seems to not trigger the censor in ChatGPT so I would actually guess for some grep for Hitler or really really fundamental no-Hitler jokes material in the training?
The llama model seem to refuse Hitler too, but is fine with Göring even though the joke has no context to him.
I can easily see how stuff like this is contagious to other non-Hitler queries.
