Anthony Greco, 18, has become the first person to be arrested for the sending of unsolicited instant messages aka spim. Greco was lured from New York to Los Angeles under the pretence of a business meeting. He was arrested upon arrival at LA airport last Wednesday. Greco allegedly sent 1.5 million messages advertising pornography and mortgages. According to US reports the recipients of the messages were all members of the MySpace.com online networking service. Greco had allegedly threatened to share his methods for spamming members of the group if MySpace.com didn't sign an exclusive marketing deal which would have legitimised the messages he was sending via the service. Greco believed he was flying to Los Angeles to close that agreement with MySpace president Tom Anderson reports silicon.com. Assistant US Attorney Brian Hoffstadt confirmed the arrest was the first criminal case brought against an individual sending spam over IM.
