Advanced 5-layer invisible spam protection for comments. No captcha, no user friction - professional spam blocking.

Access Ghost Trap - Go to settings in the admin sidebar and select GhostTrap.
GhostTrap provides sophisticated invisible spam protection using a comprehensive 5-layer detection system. Legitimate users comment normally while automated spam is silently blocked through advanced timing analysis, cryptographic validation, and behavioral detection.
All protection operates invisibly – no captcha, no puzzles, no delays. Users with JavaScript enabled see normal comment forms, while those with disabled JavaScript get simple year validation. Protection effectiveness remains high in both scenarios.
No external services, no tracking, no personal data collection beyond standard WordPress comment processing. All spam detection happens locally on your server.
Built upon the original Anti-spam plugin foundation by webvitaly, with comprehensive modernization, enhanced detection layers, and professional admin interface for current WordPress compatibility.
