The story about phone number stations posted to Craigslist has been mentioned here before. This is one of those interesting little mysteries. The hearsay only adds to it..

People have suggested that the messages are pranks, or are some sort of commercial gimmick. But at least one person, who is in the U.S. military, says he sent a copy of one of the messages up the chain of command and was promptly notified that it was classified and he wasn’t cleared to know anything further about it. I don’t know whether this is standard operating procedure for any encrypted message or whether it indicates that there’s something to be found.
