<h4>USE OF 3RD PARTY SERVICES</h4>
<p>VisualWP Cloudflare Turnstile relies on <a href="https://www.cloudflare.com/products/turnstile/" rel="nofollow ugc">Cloudflare Turnstile</a>, a 3rd party API that connects to Cloudflare servers to generate the anti-spam field that appears on the WordPress login form, register form, comment form and any Ninja Form that the field is manually added to. The anti-spam check will not work if website traffic to Cloudflare servers is blocked or impeded. Cloudflare has to look at some session data (like headers, user agent, and browser characteristics) to validate users without challenging them.

VisualWP Cloudflare Turnstile – Easy Anti-Spam alternative to CAPTCHA

Increase security and protect against bots, spammers and hackers with Cloudflare Turnstile, a friendly, free CAPTCHA replacement

LukaCodes

<p><strong>LukaCodes AntiSpam Shield</strong> is a lightweight, no-bloat plugin that protects your WordPress comment section <strong>and contact forms</strong> from spam. Five independent tools, one settings page. <a href="https://lukacodes.com/comment-shield-docs/" rel="nofollow ugc">Read the full documentation</a>.</p>
<ul>
<li><strong>Disable Website Field</strong> — Removes the URL/website field from the comment form. Works with all themes, including those that hardcode the field (CSS fallback included).</li>
<li><strong>Strip Links from Comments</strong> — Automatically removes all <code><a href></code> hyperlinks from comment content — both on display and before saving to the database. Spammers get zero benefit from posting links.</li>
<li><strong>reCAPTCHA v3</strong> — Adds Google’s invisible bot-score protection. No checkbox, no puzzle, no friction for real users. Bots are silently blocked server-side.</li>
<li><strong>Cloudflare Turnstile</strong> — A privacy-friendly CAPTCHA alternative. Mutually exclusive with reCAPTCHA v3 — enabling one automatically disables the other.</li>
<li><strong>Login Shield</strong> — Adds CAPTCHA to the WordPress login form (<code>wp-login.php</code>). Stops brute-force bots silently.</li>
<li><strong>Registration Shield</strong> — Adds CAPTCHA to the WordPress registration form. Blocks bot account creation.</li>
<li><strong>WPForms Integration</strong> — Apply the same CAPTCHA protection to WPForms Lite — using the same keys you already configured, no extra setup.</li>
</ul>
<p>All features are <strong>independent</strong> — enable only what you need.</p>
<h4>Login & Registration Shield</h4>
<p>Version 1.1.2 adds CAPTCHA protection to <code>wp-login.php</code>:</p>
<ul>
<li><strong>Login Shield</strong> — Hooks into <code>wp_authenticate_user</code> for server-side verification after credentials are checked. Returns a <code>WP_Error</code> if CAPTCHA fails — WordPress displays it as a normal login error.</li>
<li><strong>Registration Shield</strong> — Hooks into <code>registration_errors</code> to add CAPTCHA validation during registration. Works alongside all other WordPress registration validations.</li>
</ul>
<p>Both are independently togglable in the settings panel. Admins already logged in are never affected.</p>
<h4>WPForms Integration</h4>
<p>Version 1.1.0 introduces CAPTCHA protection for <strong>WPForms Lite</strong>:</p>
<ul>
<li>Hooks into <code>wpforms_display_submit_before</code> to inject the CAPTCHA widget before the submit button.</li>
<li>Hooks into <code>wpforms_process</code> for server-side token verification.</li>
<li>Works with both reCAPTCHA v3 (invisible) and Cloudflare Turnstile (visible widget).</li>
</ul>
<p>Note: WPForms Pro includes its own native CAPTCHA integration — this feature is intended for <strong>WPForms Lite</strong> users only.</p>
<h4>Why AntiSpam Shield?</h4>
<p>Most anti-spam plugins are heavy, require accounts, or add ugly CAPTCHAs. LukaCodes AntiSpam Shield is different:</p>
<ul>
<li>~30 KB total — no external libraries, no jQuery dependency</li>
<li>Settings page with <strong>live key testing</strong> — verify your reCAPTCHA or Turnstile keys before enabling</li>
<li><strong>Link stripping preview</strong> — paste any comment text and see exactly what gets removed</li>
<li>Graceful fallback: if Google’s or Cloudflare’s API is unreachable, comments are held for moderation (never lost)</li>
<li>Trusted users (administrators) bypass CAPTCHA checks automatically</li>
<li><strong>Mutual exclusion</strong>: reCAPTCHA v3 and Cloudflare Turnstile cannot be active at the same time</li>
<li>WP Coding Standards compliant — fully escaped output, nonce-protected AJAX</li>
</ul>
<h4>reCAPTCHA v3 — How it works</h4>
<p>When a visitor submits a form, JavaScript silently requests a score token from Google. The token is sent with the submission and verified server-side against your minimum score threshold (configurable from 0.1 to 1.0). No user interaction required.</p>
<h4>Cloudflare Turnstile — How it works</h4>
<p>A Turnstile widget is rendered inside the form. When the visitor completes the challenge, a token is submitted and verified server-side against the Cloudflare API.</p>
<h3>Third-Party Services</h3>
<p>This plugin optionally uses the following third-party services:</p>
<h4>Google reCAPTCHA v3</h4>
<p>A service provided by Google LLC.</p>
<ul>
<li><strong>What it does:</strong> Detects bots and spam on your comment form and contact forms without user interaction.</li>
<li><strong>When data is sent:</strong> Only when reCAPTCHA v3 is enabled. A token is sent to <code>https://www.google.com/recaptcha/api/siteverify</code> on each form submission.</li>
<li><strong>What data is sent:</strong> The visitor’s IP address and a reCAPTCHA token.</li>
<li><strong>Google Privacy Policy:</strong> https://policies.google.com/privacy</li>
<li><strong>Google Terms of Service:</strong> https://policies.google.com/terms</li>
</ul>
<h4>Cloudflare Turnstile</h4>
<p>A service provided by Cloudflare, Inc.</p>
<ul>
<li><strong>What it does:</strong> Presents a privacy-friendly CAPTCHA widget on comment and contact forms.</li>
<li><strong>When data is sent:</strong> Only when Cloudflare Turnstile is enabled. A token is sent to <code>https://challenges.cloudflare.com/turnstile/v0/siteverify</code> on each form submission.</li>
<li><strong>What data is sent:</strong> The visitor’s IP address and a Turnstile token.</li>
<li><strong>Cloudflare Privacy Policy:</strong> https://www.cloudflare.com/privacypolicy/</li>
<li><strong>Cloudflare Terms of Service:</strong> https://www.cloudflare.com/website-terms/</li>
</ul>
<p>Both services are entirely optional. If you do not enter API keys or enable either CAPTCHA, no data is sent to any third party.</p>
