A $1 billion lawsuit filed today promises to open up a new front in the battle against spam: It targets not just spammers, but — for the first time — also those responsible for harvesting e-mail addresses on behalf of spammers.

The lawsuit, filed in the U.S. District Court in Alexandria, Va., is one of the largest of its kind and is being filed on behalf of Project Honey Pot members in over 100 countries. Project Honey Pot is a service provided by Park City-Utah based anti-spam company Unspam Technologies Inc.

“If you’ve harvested e-mail addresses or sent spam in the last two years, chances are you’re on our radar screen and we’re coming after you,” a note posted on the Project Honey Pot Web site said today.
