[OPEN] Excessive autonomous "troll teh forums" action

I have basegame, all expansions, all gamepacks and stuffpacks except for: Eco Lifestyle, Journey to Batuu, Nifty Knitting, Moschinno Stuff, Tiny Living and My First Pet.

I've had this issue with all sims, in both a modded game and mod and cc-free game. Either they have the geek trait, high programming skill or low fun/social need.

• With low fun and/or social, instead of playing a computer game, they choose to troll the forums
• Instead of programming/practice writing/search the web/chat online, they choose to troll the forums
• Instead of watching tv or dancing to radio, they choose to troll the forums

If I don't..

• restrict access to a computer
• monitor every sims activity carefully
• or turn autonomy off

Then eventually every sim will have a few Mischief points from this, and I've had one occasion where a sim made it to level 5 mischief skill all on his own from trolling the forums and then autonomously choosing mischief interactions with other members of the household, when I was taking care of other sims and ignoring this one.

I have...

• Removed mods to test
• Repaired my game to test
• Removed my saves/tray and deleted the sims 4 folder to generate a fresh folder

What do I expect?

I don't understand why a mischief related interaction ("Troll teh forums") is associated with the Geek trait or high programming skill. I associate mischief interactions with the Goofball, Mean and Evil trait, OR with the playful moodlet.
