I read a posting on either slashdot, or
www.wilwheaton.net where a spammer had logged on bragging about all the money he had made from spamming people, and he was promtply hacked (to find his address) and signed up for every junk snail-mail mailing they could find, he recieved somthing along the lines of 1000lbs of spam snailmail a day as a result.
