Believe it or not, there was an episode of The Closer that followed this line. A woman's boyfriend used the woman's computer to put an ad on a Craiglist-type service saying she wanted to be raped and that she would leave a key under a rock by the door. She ended up being killed when she fought back against her assailant.
I can't imagine the victim of this assault will ever be able to trust anyone again as long as she lives.
There was an episode of SVU similar to this.
It was a bitter ex boyfriend who was stalking the woman though and used her e-mail on a rape fantasy chat room and set it up.
