I send them to my vampire retirement retreat. They will live out the rest of their days in an alternative dimension where time flies by faster for them (and of course, the vampire caretakers are unaffected) as retired Sims serving as vampire snacks volounteers. If said Sim happens to be a vampire, the vampires will force a cure upon him, then he'll become a snack as well.
(Not many of my Sims gets this honor, though. It's usually a townie that gets the spot, if they manage to anger me by flirting with one of my married Sims or breaking into my house yet again). Sometimes, awful fashion nets them a place. I'm a forgiving creator, but examples must be set.
