<p><strong>GhostTrap</strong> 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.</p>
<h4>5-Layer Protection System</h4>
<ul>
<li><strong>Timing Analysis</strong> – Detects submissions too fast for human interaction</li>
<li><strong>Cryptographic Signatures</strong> – Prevents replay attacks and form manipulation</li>
<li><strong>Year Validation</strong> – JavaScript-enhanced field verification</li>
<li><strong>JavaScript Detection</strong> – Ensures legitimate browser interaction</li>
<li><strong>Honeypot Fields</strong> – Multiple hidden traps catch automated bots</li>
</ul>
<h4>Professional Features</h4>
<ul>
<li><strong>Enhanced Admin Interface</strong> – Professional statistics dashboard with custom branding</li>
<li><strong>Real-time Statistics</strong> – Track protection effectiveness with detailed blocking metrics</li>
<li><strong>Configurable Timing</strong> – Adjust detection sensitivity from 5-300 seconds</li>
<li><strong>WordPress 6.4+ Compatible</strong> – Full support for block themes and FSE</li>
<li><strong>Admin Bar Integration</strong> – Quick spam statistics for administrators</li>
<li><strong>Screen Options Control</strong> – User-configurable interface elements</li>
</ul>
<h4>Zero User Friction</h4>
<p>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.</p>
<h4>Performance Optimized</h4>
<ul>
<li><strong>Lightweight JavaScript</strong> – Only 2KB, loads exclusively on comment pages</li>
<li><strong>Smart Script Loading</strong> – Conditional loading based on comment form presence</li>
<li><strong>Minimal Database Impact</strong> – Efficient storage with optional spam archiving</li>
<li><strong>Browser Compatibility</strong> – Works across all modern browsers with graceful degradation</li>
</ul>
<h4>GDPR Compliant</h4>
<p>No external services, no tracking, no personal data collection beyond standard WordPress comment processing. All spam detection happens locally on your server.</p>
<h4>Attribution</h4>
<p>Built upon the original Anti-spam plugin foundation by webvitaly, with comprehensive modernization, enhanced detection layers, and professional admin interface for current WordPress compatibility.</p>
