I have the mischief activity set to dislike on every SIM since I started playing the game because I literally hate it... in the game and in real life. Recently, EVERY SINGLE SIM has acquired the skill and uses it on all my other SIMs. I have even deleted Sims because they became too obnoxious to be around. Please disable this undocumented feature you have recently added to the game.
I found this to be a problem too and the only solution I found was to have my sims dive in and enjoy it and set them to like mischief, deception and maliciousness because of the insults. And then I had a nasty surprise when I decided to do an aspiration on it which required using the voodoo doll. I did not know this would cause a sim to pick up the Thanatology skill which is relationship wrecking. I had to add mccc back to my game a few days ago because I could find no other way to go through my sims and remove that skill from everyone. So for those that didn't know that like I did not, AVOID USING THE VOODOO DOLL!!!!
