You can always control the traits, lifestyles, likes and dislikes in this game.
Nobody is forcing mischief gameplay on you.
Toggles are ment to be controlled with all the DLC.
Trial and error is a good way to omit mischievous behavior in the game.
It's a game that you have to controll while making the right decisions for your sims and based on your playstyle.

Sadly nothing is stopping sims from being obsessed with computers, mainly to troll the forums. You have to lock them out of the computer to stop them from doing that.
Likes and dislikes do nothing but add a useless buff or debuff but don't alter gameplay. Now your sims just get annoyed by the stuff they still do automatically but won't stop doing it. If they hate violins they will still go out of their way to listen to it, even if a housemate is three floors underground in a bunker playing it.

That's the point. They ARE. I have the same problem as OP. I have set my main characters as disliking Mischief and Mean interactions. They autonomously Troll the Forums and use Mischief and Mean socials anyway. This is even with Zero mods installed. It's a known issue that's been ongoing for years now, and they won't fix it.
