I dislike comedy and I literally had to tune it out of every file that would level comedy because Sim's disliking it wasn't enough. So I know how you feel, I only have 1 Sim I allow Mischief and it is only inherit due to the fact I have them learning the school of Mischief for my storyline.
But what about Proper Trait? It is suppose to disapprove of mischief.
I also use the Lock Skill mod, it allows me to lock Sims from learning any skills I don't want them too. But it does announce every time (including repeating) you learned the skill (when you haven't) when using an interaction that levels it. But I rather that—then an unwanted skill. This has been a game saver for me, I hate when my Sims learn things I didn't want them to.
So far I have been mod free due to reading about lots of issues with mods. I do use cheats, but so far no cheat has worked. I turned off autonomy and that stopped it, but it also stopped the enjoyment of the game. Probably going to give up and just quit playing... come back later and see if they fixed it.
They'd need to overhaul autonomy like this and/or likes/dislikes to actually whitelist/blacklist from autonomous use. I mean I hope they do, it would solve a lot of issues for a lot of people.
