I wouldn't say I "ban" these things, but I won't put them in my houses anymore until sims stop obsessing over them: Sinks, globe bar, bulletin board, high chairs, gaming rigs, card tables, doll houses, talking toilets, bubble blower, laundry appliances. I'm actually quite sure I forgot some too.
Computers are locked behind doors, so only household members can get to them. Because we all know how it goes, you invite friend in, they head straight for the computer and you don't see them again until they thank you for "hanging out with me".
