This week I got an email from a friend of mine asking for money since he was stranded overseas because his wallet had been stolen. Although the whole scenario sounded reasonable (I have had friends that this has happened to and this friend does do some traveling), I was skeptical since I knew of this scam. I used a different email address I had for him and confirmed it was indeed a scam. Please see this article about what these scam/spam emails look like and some hints on how to spot the scam: http://www.net-security.org/secworld.php?id=9150
