SPAM is an economic problem, not a technical one. And this lawsiut could be one of the first steps to solve the problem, if it succeeds:
Some of the worst spammers in the United States could be in for a rude surprise shortly, as Unspam Technologies has taken the first steps in tracking them down, with help from the ISPs.
The company filed a lawsuit yesterday in the Eastern District of Virginia seeking the identities of spammers under the U.S. CAN-SPAM Act and the state of Virginia’s own anti-spam statue. The suit seeks damages that could potentially reach $1 billion, but Unspam said it would be happy with driving spammers out of business.
