Advanced Anti-SPAM Plugin for miniBB (reCaptcha, Spammer Slapper)

This is the "Advanced Anti-SPAM" plugin for miniBB 2.x. It uses the reCaptcha service to add a challenge to the post and reply form. Secondly, after a valid Captcha, it uses the Spammer Slapper service for additional anti-spam protection.

Additional options can be passed to the Spammer Slapper by editing the 'setup_anti_spam.php' configuration file. (see the Spammer Slapper website for information). These two services together will have a dramatic effect on the elimination of SPAM in your forums.
