Submission + - Building a better spam trap (nytimes.com)
SpiritGod21 writes: "Steven T. Kirsch, the developer of the optical mouse, has been thinking about the spam problem for a number of years. After filing several patents covering other approaches, Mr. Kirsch hit on the idea underlying his latest invention, Abaca, quite by accident.
The approach underlying the Abaca technique is the recognition that the ratio of spam to legitimate e-mail is individually unique. It is also a singular identifier that a spammer cannot manipulate easily. By assessing the combined reputations of the recipients of any individual message, the Abaca system determines the "spaminess" of a particular message. Mr. Kirsch asserts this provides a high degree of accuracy in deciding whether the message is spam."
