Per-IP/hour
Sliding window rate limit. The first request from a new IP always passes; the limit kicks in on subsequent ones inside the same hour.
Feature
Rate limiting & submission caps
Cap submissions per IP per hour, total submissions per form, or block duplicates within a session.
Part of Core Forms — every premium WordPress form feature in one plugin, one license, unlimited sites.
Three layers of rate-control: per-IP-per-hour, total submission count cap, and duplicate-blocking by session. Each is per-form and stacks cleanly with the spam-protection stack.
