After allegedly sending 1.5 million "spim" messages on MySpace.com's online network to mobile devices, 18 year old Anthony Greco allegedly threatened to spread his methods for spimming the network unless MySpaces.com agreed to an exclusive agreement, effectively rendering his spam legitimate. But instead of finding MySpaces.com president Tom Anderson waiting for him at the airport, he was arrested, according to a Silicon.com report. A federal prosecutor confirmed that this is the first arrest of an IM spammer.
