Microsoft researcher Cormac Herley seeks to answer one of the basic questions of internet life in his paper, Why do Nigerian scammers say they are from Nigeria? Getting an email from a deposed Nigerian prince sends off warning bells to just about everyone, so why do scammers continue to use such outlandish stories from a location infamous for advance fee fraud? Herley says that scammers don't want anyone but the most gullible — and therefore the most likely to follow through — to respond to the emails because it costs scammers time, money, and effort to continue past the first email. The point is to weed out those who will back out with the initial email, to focus their effort on those more likely to fall for the entire scheme. Now, if you'll excuse us, we'll be off responding to each and every prince just looking for a place to send his millions.
