Invisible to genuine users. Starts behavioural scoring immediately.

They click Submit. The 4-layer check begins.

4-layer check runs in <200ms
Identity · Behaviour · Device Fingerprint · Duplicate — all simultaneously.
✅ Genuine Lead
Passes through normally
Reaches your CRM. Triggers conversion tracking. Google records it as a real buyer signal.
✗ Fake Lead
Blocked permanently
No CRM entry. No conversion tracked. Platform never learns from it. Device fingerprinted forever.

The Honest Part

The First Submission Always Goes Through.

The very first submission from any new device is intentionally allowed through. That's how we capture their full device fingerprint — canvas hash, device characteristics, IP range, behaviour pattern — everything we need to block them permanently.

Think of it as a trap. The first contact is the capture. Every return visit from that device — different IP, different VPN, different number, incognito mode — still blocked forever.

Why this matters

If we blocked before the first submission, we'd have no fingerprint data. The attacker would just switch VPNs and keep going indefinitely. By letting the first one through, we permanently identify the device behind it — and they can never submit again from that device, no matter what they change.
