IBM set to use spam to attack spammers

"IBM unveiled a service Tuesday that sends unwanted e-mails back to the spammers who sent them.

The new IBM (Research) service, known as FairUCE, essentially uses a giant database to identify computers that are sending spam. E-mails coming from a computer on the spam database are sent directly back to the computer, not just the e-mail account, that sent them."
