From Datamation:
Can you trust a major corporation to keep your e-mail address out of spammers’ hands after you fill out the company’s unsubscribe form?
Not always, according to a service that tracks what happens when addresses are submitted to unsubscribe mechanisms on the Web.
I wrote last week that a service called Lashback LLC has tested some 170,000 different “remove me” procedures that it’s found on the Internet. This small antispam firm says it’s already caught some big fish in its net.
