About GhostTrap
From the official readme · v1.0.3Description
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.
5-Layer Protection System
- Timing Analysis – Detects submissions too fast for human interaction
- Cryptographic Signatures – Prevents replay attacks and form manipulation
- Year Validation – JavaScript-enhanced field verification
- JavaScript Detection – Ensures legitimate browser interaction
- Honeypot Fields – Multiple hidden traps catch automated bots
Professional Features
- Enhanced Admin Interface – Professional statistics dashboard with custom branding
- Real-time Statistics – Track protection effectiveness with detailed blocking metrics
- Configurable Timing – Adjust detection sensitivity from 5-300 seconds
- WordPress 6.4+ Compatible – Full support for block themes and FSE
- Admin Bar Integration – Quick spam statistics for administrators
- Screen Options Control – User-configurable interface elements
Zero User Friction
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.
Performance Optimized
- Lightweight JavaScript – Only 2KB, loads exclusively on comment pages
- Smart Script Loading – Conditional loading based on comment form presence
- Minimal Database Impact – Efficient storage with optional spam archiving
- Browser Compatibility – Works across all modern browsers with graceful degradation
GDPR Compliant
No external services, no tracking, no personal data collection beyond standard WordPress comment processing. All spam detection happens locally on your server.
Attribution
Built upon the original Anti-spam plugin foundation by webvitaly, with comprehensive modernization, enhanced detection layers, and professional admin interface for current WordPress compatibility.

Frequently asked questions
How effective is the 5-layer system?
GhostTrap blocks virtually all automated spam while maintaining zero friction for legitimate users. The multi-layer approach ensures that even if bots bypass one detection method, additional layers provide backup protection.
What happens if users disable JavaScript?
Users with disabled JavaScript (less than 1% of visitors) see a simple year validation field. They enter the current year to submit comments. Protection effectiveness remains high through server-side validation layers.
Does it impact site performance?
No measurable impact. JavaScript loads only on pages with comment forms, the detection process adds minimal server processing time, and database queries are optimized for efficiency.
Can I see what spam was blocked?
Yes. Enable “Save blocked spam” in Settings → GhostTrap to store blocked submissions in WordPress spam folder for review. This helps fine-tune timing settings if needed.
Is it compatible with comment plugins?
GhostTrap works with standard WordPress comment systems, AJAX comment loading, and most comment enhancement plugins. It detects comment forms dynamically and applies protection automatically.
What about trackbacks and pingbacks?
Trackbacks are blocked (high spam potential, rarely legitimate) Pingbacks are allowed (verified WordPress-to-WordPress communication)
How do I adjust detection sensitivity?
Visit Settings → GhostTrap to configure timing thresholds. Default 15-second minimum works well for most sites. Increase for slower readers, decrease for higher security on high-traffic sites.
Does it work with block themes?
Full compatibility with WordPress block themes, Full Site Editing, Gutenberg comment blocks, and classic themes. The protection system adapts to various comment form implementations.
