Blue Squirrel Inc. announced the availability of Spam Sleuth 2.0 software, which it describes as a "turbo-charged" version of its original product.
The new version includes "E-mail Stamps," a system Blue Squirrel has set up that makes spammers pay users through online payment provider PayPal for sending spam messages. It also has an automated statistical analysis tool.
Similar spam programs that assign monetary penalties to spammers have been introduced recently. Vanquish Inc. just launched a software product that fines marketers for spam.
Blue Squirrel plans within the next month to introduce an enterprise version of Spam Sleuth 2.0. It will charge a one-time licensing fee for the product based on the number of users.
