OptionWeb

<p>OW Forms is a modern WordPress form builder for sites that prioritize performance, accessibility, and GDPR compliance. Built by OptionWeb for production use on client sites, it ships with a JSON-driven schema engine, a REST-based submission pipeline, and a curated set of 16 field types — text, email, tel, URL, number, textarea, select, radio, checkbox, checkbox-group, date, time, datetime, file upload, hidden, and rating — plus auto-injected GDPR consent and anti-spam fields.</p>
<p>The anti-spam stack runs four layers in parallel: a visually-hidden honeypot input that bots fill but humans never see, a time-trap that rejects submissions completed faster than a configurable threshold, a multi-provider CAPTCHA layer (Cloudflare Turnstile, Google reCAPTCHA v3, hCaptcha, or Friendly Captcha), and optional OW Shield IP reputation scoring with a disposable-email blocklist. Every signal is logged so you can tune thresholds without flying blind. Submissions that score above 80 are silently rejected — no error message, no honeypot leak.</p>
<p>GDPR compliance is native, not bolted on. Every form gets a consent checkbox linked to your privacy policy, IP addresses can be stored pseudonymized or not at all, user agents are SHA-256 hashed by default, and a daily cron purges submissions older than your retention window (CNIL default: 1095 days). When OW Consent is active, OW Forms wires into its DSAR endpoint — erasure requests automatically delete matching submissions by email hash, with full audit trail. Submission emails are SHA-256 hashed with a plugin-owned salt (option <code>owfo_dsar_salt</code>, generated once at activation) so the database never holds plaintext PII linkable across systems, and DSAR erasure keeps working even after <code>wp config shuffle-salts</code>.</p>
<p>The one-click Contact Form 7 importer parses every CF7 form in your database, builds the equivalent OW Forms schema (preserving recipient, subject, and field types), and rewrites every <code>[contact-form-7 id="..."]</code> shortcode in your posts to <code>[owfo_form id="..."]</code>. Email notifications support HTML or plain text with <code>{{token}}</code> interpolation, optional auto-reply, signed outbound webhooks (HMAC-SHA256), and a Gutenberg block in addition to the shortcode and REST API.</p>
<h3>External services</h3>
<p>OW Forms relies on optional third-party CAPTCHA services to protect form submissions<br />
from spam. <strong>None of these services are contacted unless you explicitly enable a<br />
CAPTCHA provider in OW Forms <span aria-hidden="true" class="wp-exclude-emoji">→</span> Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Anti-spam.</strong></p>
<p>The OW Shield integration is fully local — when the OW Shield plugin is installed<br />
and active on the same site, OW Forms reads its IP reputation score from the local<br />
database/cache. No request leaves your server for this lookup; OW Shield itself<br />
may contact its own reputation service, which is disclosed in the OW Shield readme.</p>
<p>The Friendly Captcha widget JavaScript is bundled with OW Forms under<br />
    assets/js/vendor/ (no external CDN is hit at page render). Source: the upstream<br />
MIT-licensed package at https://github.com/FriendlyCaptcha/friendly-challenge —<br />
the files shipped here are the official npm <code>friendly-challenge@0.9.18</code> build<br />
outputs (<code>widget.module.js</code> and <code>widget.module.min.js</code>, unmodified, renamed to<br />
    friendly-challenge-0.9.18.module.js / <code>friendly-challenge-0.9.18.module.min.js</code><br />
to make the version explicit in the filename). Both the minified and the<br />
human-readable non-minified source are shipped per WordPress.org Plugin Check<br />
requirements.</p>
<p>When a CAPTCHA provider is enabled, OW Forms loads the vendor’s JavaScript widget<br />
on pages that render a form, and posts the challenge solution back to the vendor’s<br />
verification API when a visitor submits the form. The data sent to the vendor is<br />
limited to: (a) the challenge token generated client-side by the vendor’s widget,<br />
(b) the visitor’s IP address (passed through to the vendor for fraud scoring), and<br />
(c) the site’s API secret key configured in the settings.</p>
<h4>Cloudflare Turnstile</h4>
<ul>
<li>What it is: a CAPTCHA / bot-mitigation service by Cloudflare, Inc.</li>
<li>When data is sent: only when <code>spam_captcha_provider</code> is set to <code>turnstile</code>, and<br />
only on form submission. The widget JS is also loaded on every page that renders<br />
a form.</li>
<li>Data sent: Turnstile challenge token, visitor IP, your Turnstile secret key.</li>

<li>When data is sent: only when <code>spam_captcha_provider</code> is set to <code>recaptcha_v3</code>, and<br />
only on form submission. The widget JS is also loaded on every page that renders<br />
a form (this is how reCAPTCHA v3 builds its risk score).</li>
<li>Data sent: reCAPTCHA token, visitor IP, your reCAPTCHA secret key. Google may<br />
also collect additional telemetry as described in their privacy policy.</li>

(Germany). No user puzzle, no tracking cookies.</li>
<li>When data is sent: only when <code>spam_captcha_provider</code> is set to <code>friendly_captcha</code>,<br />
and only on form submission. The widget JS itself is bundled with OW Forms (not<br />
loaded from an external CDN); only the verification request reaches the vendor.</li>

</ul>
<h4>Outgoing webhook (admin-configured)</h4>
<ul>
<li>What it is: a URL of your choosing that OW Forms POSTs to after each submission.<br />
No data leaves your site until you fill the <code>webhook_url</code> setting in OW Forms <span aria-hidden="true" class="wp-exclude-emoji">→</span><br />
Settings <span aria-hidden="true" class="wp-exclude-emoji">→</span> Notifications.</li>
<li>When data is sent: on every form submission, immediately after the admin<br />
notification email is dispatched. Non-blocking — your visitor’s submission<br />
response is not delayed by the webhook endpoint’s latency.</li>
<li>Data sent: form id, submission id, sanitized field payload (the same data<br />
stored in your <code>wp_owfo_submissions</code> table), site URL, ISO 8601 timestamp.<br />
If a webhook secret is configured, an <code>X-OWFO-Signature</code> HMAC-SHA256 header<br />
is added so the receiver can verify the payload origin.</li>
<li>Vendor: whoever owns the URL you configured. OW Forms has no built-in vendor<br />
for this — it is your responsibility to ensure the receiving endpoint complies<br />
with applicable privacy regulations for your submissions.</li>
</ul>


OW Forms

Modern, lightweight WordPress form builder with native GDPR compliance, anti-spam stack, and Contact Form 7 importer.

GravityKit

<p>This Gravity Forms add-on blocks spam using a non-obtrusive anti-spam measure and can email a spam report summary.</p>
<h3>Spam blocking for Gravity Forms</h3>
<p>To get started, all you need to do is activate the plugin!</p>
<h3>Is the Gravity Forms honeypot field not working for you? 🍯 🐝</h3>
<p>Zero Spam is better than the Gravity Forms anti-spam honeypot field. If you’re getting spammed, try this plugin.</p>
<h3>Use this plugin instead of reCaptcha</h3>
<p><strong>reCaptcha is user-hostile!</strong> Use this instead! Users don’t need to click stoplights, crosswalks, or bicycles when you use this plugin to stop spam.</p>
<h3>Enable or disable filtering per form</h3>
<p>If you only want the plugin for specific forms, that’s possible! The plugin adds a simple “Prevent spam using Gravity Forms Zero Spam” setting to each form (requires Gravity Forms 2.5 or newer).</p>
<h3>Spam report emails</h3>
<p>Spam summary report emails are disabled by default. Once enabled, a spam summary that includes the number of entries per-form will be sent via email.</p>
<p>Choose whether you want to be notified after the number of entries reaches a threshold (e.g. 10 spam entries) or after a certain number of days (e.g. every week). If there are no spam entries, no report will be sent.</p>

Gravity Forms Zero Spam

It helps way more than Gravity Forms' built in features, and it's nice to try invisible options before making users deal with Captcha quizzes. :)

Appreciate this plugin a lot!

Besides its simple approach, David Walsh’s “Zero Spam” technique, it works well.

Simple and effective

An amazingly simple yet successful strategy, this plugin captures pretty much all automated spam with little chance of false positives. No need to bother people with nasty CAPTCHAs, just install this plugin enjoy the ensuing peace.

Sends automated spam to the bit bucket

Enhance your Gravity Forms to include anti-spam measures originally based on the work of David Walsh's "Zero Spam" technique.
