Incidentally, working at a company which provides computer support to various sundry customers, we've had numerous occasions where we find home-made porn on people's computers. It's always fun. Some of it isn't very attractive, though.
We once found pictures of a woman of about 170 lbs outside shooting a rifle with no pants on. Believe you me, the novelty of truely ametuer porn wears off quickly when you realize that all those advertisements for "ex-girlfriend revenge" websites are professionally done and/or doctored. Real people aren't attractive.
