How It Works
SpamJam uses multiple layers of protection:
Salted Honeypot Fields – Per-site randomized hidden fields that only bots fill out
Timing Check – HMAC-signed server timestamp detects instant bot submissions
Weighted Scoring Engine – Signals combine into a score; hard signals block immediately, soft signals accumulate; gray-zone submissions are held for moderation
Referrer Checking – Verifies submissions come from your site
Hash Validation – Cryptographic HMAC verification of form integrity
Keyword Filtering – Blocks known spam patterns
All of this happens invisibly in the background. Your legitimate users never see a captcha or verification step.
Privacy First
SpamJam doesn’t send your data to third-party services. Everything happens on your server, keeping your users’ information private and your site GDPR-compliant.
