Forcing this kind of safety into the models and harnesses is a mistake. I think the strategy of post hoc moderation is the right one. Trying to prevent evil ideological activities as they transpire is a cursed mission. Let someone who is genuinely doing a naughty thing accumulate a meaningful body of evidence and then send in Mr Holmes (the FBI / police). Attempting to prevent wrong think at every token is too granular. We have systems designed to handle the possibility that crime and punishment may occur at separate moments in time. Most people don't go around murdering because the eventual consequences are pretty severe. Just because an AI gave you advice doesn't magically make those existing consequences vanish.
Also, humans convincing their friends to do crime might also share some responsibility too, no? Bad advice is not great either, even if the human consents.
