I'm adding a prior art section to the Legal page at WeCanStopSpam.org.

More prior art to any attempted patents on challenge-based anti-spam systems. As noted previously, MailFrontier says they have a patent pending on theirs.

The prior art link above points to an archive of a service that was apparently working on November 27, 1999 and, no doubt, earlier.

Thanks to a personal email from Faisal N. Jawdat.
