nukeSPAM(tm) enables site using the RavenNuke(tm) content management system (CMS) and other PHP-Nuke distributions to prevent user registration by known spammers. It features:

• Configurable blocking via 3 public spam databases and 14 DNS blacklists
• Advanced logging, reporting and false positive resolution
• Advanced whitelist maintenance
• Administrator function to check if username, email and / or IP address are blocked

Although nukeSPAM(tm) administration automatically creates the necessary database tables, integration with user registration requires code changes (instructions are included for RavenNuke(tm) Your Account).

nukeSPAM(tm) can be downloaded here. Download requires 7-zip. Free membership is required to download.
