No, not my Sims, but I torture and antagonise the other Sims by-proxy with my Evil Sim.
I've given him the Evil, Mean Spirited, Insane, Inappropriate and Hates Children traits, which makes him the biggest arsehole in all of SimTown.
I mainly troll the other Sims in aesthetic ways, by dressing my Sim in outrageously garish clothing and not washing, or in architectural ways, like making painting the inside of my front room, carpets and furniture with a black space pattern, so it messes with their heads and sends them mad.
I've also use full length mirrors to great effect in making my house seems to be different dimensions than what it really is, plus I've made all the external walls in my bathroom out of full length windows, made the internal walls mirrors, and made the only light a spot light shining on the toilet, so the entire neighbourhood can see my Sim taking a dump (I just wish he would wave at them as they walked past).
Hilariously enough, when I leave him to his own devices, his favourite activity seems to be using the computer to troll internet forums, and due to his traits he seems to seek out other Sims children wearing just his skimpy, cartoon animal patterned bathing costume, and once he's made them cry with his insane and creepy babbling, he beats up their enraged parents and then laughs at their misfortune.
This Sim has sort of backfired on me though, I've truly made a monster, because I made the mistake of making my "proper" Sim (based on me) in the same game world as my "Evil Troll Sim", which means that when I was trying to progress in the game normally, the evil insane Sim would keep fucking shit up for me, it's like the game purposefully made my 2 created Sims interact more with each other, and I'd have to turn round and walk the other way if I saw him coming or leave my house via the back door every time he visited.
