Sporkie is a challenge/response spam email filter. It uses CAPTCHAs (randomly generated, distorted images of numbers) in order to verify that a person sending email is human. It works in the same manner as the ASK project, except that Sporkie uses CAPTCHAs. The main advantage to using CAPTCHAs is that it catches automated spam bots that don't spoof their email address. With ASK, such bots would get through the system. Sporkie is provided under the OSCL Type-C license.
