LanceDesk Form Guard protects contact and registration forms from spam using a two-layer defense system:
- Layer 1 — Heuristics: Fast deterministic checks for BBCode injection, link stuffing, honeypot fields, and too-fast submissions.
- Layer 2 — AI Analysis: Optional semantic spam classification via Groq, OpenAI, or Anthropic.
Supports WPForms, Contact Form 7, Gravity Forms, Quform, and Ninja Forms. Logs blocked and quarantined submissions with hashed IP and email values for privacy.
