WS Form includes a range of spam protection tools for forms in WordPress. You can reduce unwanted submissions with validation, blocking rules, throttling, anti-bot fields, and third-party spam protection services.
Built-in options include deduplicating form submissions, custom server-side validation, form validation, HoneyPot, NONCE, and IP throttling. You can also block submissions by keyword, IP, domain name, and user agent.
WS Form also integrates with services including Akismet, OpenAI Moderation, CleanTalk, Clearout, OOPSpam, Cloudflare Turnstile, hCaptcha, reCAPTCHA, and CaptureFox.
Spam checking with Akismet, reCAPTCHA Version 3, and hCaptcha stores a spam score against submissions. Scores run from 0% to 100%, are shown as a colored circle, and submissions deemed as spam are moved to the Spam folder on the submissions page.
