An 18 year old teenager in the US has become the first person to be charged on suspicion of sending unsolicited instant messages - or spim. Anthony Greco was arrested upon arrival at Los Angeles International Airport last Wednesday. He has allegedly sent 1.5 million messages advertising pornography and mortgages. Greco had also tried to get the MySpace.com online networking service (whose customers comprised most of Greco's victims) to sign an exclusive marketing deal that would have legitimized the messages he was sending, by allegedly threatened to share his methods for spamming the service with other parties. Allegedly, Greco had been spimming since autumn 2004. This is the first, but by no means the last of such cases.
