+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.")
