Adding to it's powerful arsenal of *-blocker tools, Earthlink has a new product in beta called Scamblocker. Lockergnome probably describes the functionality best in this post.
"Imagine you had a Web browser that said when you typed in a new address, “The Internet site you’re about to visit is known to steal credit-card numbers and use them in unauthorized ways.”
I'd certainly use that. Apparently the application is available from Earthlink right now, although the database is not yet very robust, I'm certainly excited to watch the further development of this product (and the inevitable products that will provide the same functionality).
Google, are you listening? Please add this functionality ASAP to my Google toolbar. Thanks.
