A couple of years ago we noticed a rash of people coming to the Ref Desk asking to fax their driver's license to an out-of-state fax number. Now normally we wouldn't pay attention to such things and would respect our patrons privacy but the coincidence was just too great not to arouse suspicion when several people (who looked and acted strung out on something) during the course of a single day asked to fax the same stuff to the same number.
Curious, I traced the fax number back to a do-it-yourself pharmaceutical website where people entered their abbreviated medical histories, received a quickie diagnosis and then were asked to fax their id's to this 'pharmacy' and they would in turn receive a prescription for popular narcotics. Unfortunately, it wasn't a scam. It turned out to be a multi-state drug ring that the F.D.A. and state pharmaceutical associations finally started to crack down on.
