LanceDesk Form Guard protects contact forms and WordPress post comments from spam using a two-layer defense system:
- Layer 1 — Heuristics: Fast deterministic checks for BBCode injection, link stuffing, suspicious image/shortener hosts, commercial/SEO cold outreach (including polite sales pitches), honeypot fields, and too-fast submissions.
- Layer 2 — AI Analysis: Optional semantic spam classification via Groq, OpenAI, or Anthropic (off by default; requires privacy acknowledgment and your API keys).
Supported integrations
- WPForms, Contact Form 7, Gravity Forms, Quform, and Ninja Forms (per-form toggles)
- WordPress Core — native post comment forms (site-wide toggle under Settings)
Blocked submissions are logged with hashed IP and email values. Legitimate submissions flow normally.
External services
