Stopping Spam without CAPTCHAs

Nothing ruins a user's experience like having to select all images with traffic lights just to join a waitlist.

CAPTCHAs are inherently hostile to users and demonstrably lower conversion rates. At Rinnode, we believe security should be invisible.

The Honeypot Approach

Our first line of defense is the _rinnode_bot_trap field. It's a hidden input field that regular users never see. However, automated scrapers and bots will almost always fill it out.

If we receive a submission with data in this field, we instantly drop it. No database hit, no email alert.

AI-Powered Content Classification

For more sophisticated human-farmed spam, we rely on AI. Every submission runs through a lightweight LLM pipeline (powered by Gemini) that looks for common spam patterns, SEO links, and suspicious language.

If a submission is flagged, it is silently marked as spam in your dashboard. You never get a notification, but you can review it later if you suspect a false positive.
