Vipul’s Razor

Vipul’s Razor is a way of broadcasting spam warnings so that others can automatically avoid the spam. Put more technically, Vipul’s Razor is a distributed, collaborative, spam detection and filtering network. Through user contribution, Razor establishes a distributed and constantly updating catalogue of spam in propagation that is consulted by email clients to filter out known spam. Detection is done with statistical and randomized signatures that efficiently spot mutating spam content. User input is validated through reputation assignments based on consensus on report and revoke assertions which in turn is used for computing confidence values associated with individual signatures.

The latest version counters the spammers’ attempts to disguise messages through minor changes to the wording by using Nilsimsa fuzzy Signatures.

Unfortunately, using it requires skill with the Perl programming language, and the documentation is written in deep Posix Geek. Somebody needs to write a Java interface to the Razor servers to make it more accessible to humans.
