Reminds me of the hard drive a guy was selling not so long ago on e-bay. He gave his reason for selling it that he didn't know when he bought it for his wife that she was planning to fill it up with the naked pictures and videos of herself he'd found on it, which she was distributing to various online boyfriends while he was at work... the advert ended saying something like "oh and in case you're wondering, I'm getting rid of her too".
Poor guy, but I suspect this happens a lot these days given the popularity of all of the online "dating" sites and what not.
