LukaCodes

LukaCodes AntiSpam Shield is a lightweight, no-bloat plugin that protects your WordPress comment section and contact forms from spam. Five independent tools, one settings page. <a href="https://lukacodes.com/comment-shield-docs/" rel="nofollow ugc">Read the full documentation</a>.
<ul>
<li>Disable Website Field — Removes the URL/website field from the comment form. Works with all themes, including those that hardcode the field (CSS fallback included).</li>
<li>Strip Links from Comments — 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>reCAPTCHA v3 — Adds Google’s invisible bot-score protection. No checkbox, no puzzle, no friction for real users. Bots are silently blocked server-side.</li>
<li>Cloudflare Turnstile — A privacy-friendly CAPTCHA alternative. Mutually exclusive with reCAPTCHA v3 — enabling one automatically disables the other.</li>
<li>Login Shield — Adds CAPTCHA to the WordPress login form (<code>wp-login.php</code>). Stops brute-force bots silently.</li>
<li>Registration Shield — Adds CAPTCHA to the WordPress registration form. Blocks bot account creation.</li>
<li>WPForms Integration — Apply the same CAPTCHA protection to WPForms Lite — using the same keys you already configured, no extra setup.</li>
</ul>
All features are independent — enable only what you need.
<h4>Login & Registration Shield</h4>
Version 1.1.2 adds CAPTCHA protection to <code>wp-login.php</code>:
<ul>
<li>Login Shield — 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>Registration Shield — Hooks into <code>registration_errors</code> to add CAPTCHA validation during registration. Works alongside all other WordPress registration validations.</li>
</ul>
Both are independently togglable in the settings panel. Admins already logged in are never affected.
<h4>WPForms Integration</h4>
Version 1.1.0 introduces CAPTCHA protection for WPForms Lite:
<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>
Note: WPForms Pro includes its own native CAPTCHA integration — this feature is intended for WPForms Lite users only.
<h4>Why AntiSpam Shield?</h4>
Most anti-spam plugins are heavy, require accounts, or add ugly CAPTCHAs. LukaCodes AntiSpam Shield is different:
<ul>
<li>~30 KB total — no external libraries, no jQuery dependency</li>
<li>Settings page with live key testing — verify your reCAPTCHA or Turnstile keys before enabling</li>
<li>Link stripping preview — 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>Mutual exclusion: 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>
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.
<h4>Cloudflare Turnstile — How it works</h4>
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.
<h3>Third-Party Services</h3>
This plugin optionally uses the following third-party services:
<h4>Google reCAPTCHA v3</h4>
A service provided by Google LLC.
<ul>
<li>What it does: Detects bots and spam on your comment form and contact forms without user interaction.</li>
<li>When data is sent: 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>What data is sent: The visitor’s IP address and a reCAPTCHA token.</li>
<li>Google Privacy Policy: https://policies.google.com/privacy</li>
<li>Google Terms of Service: https://policies.google.com/terms</li>
</ul>
<h4>Cloudflare Turnstile</h4>
A service provided by Cloudflare, Inc.
<ul>
<li>What it does: Presents a privacy-friendly CAPTCHA widget on comment and contact forms.</li>
<li>When data is sent: 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>What data is sent: The visitor’s IP address and a Turnstile token.</li>
<li>Cloudflare Privacy Policy: https://www.cloudflare.com/privacypolicy/</li>
<li>Cloudflare Terms of Service: https://www.cloudflare.com/website-terms/</li>
</ul>
Both services are entirely optional. If you do not enter API keys or enable either CAPTCHA, no data is sent to any third party.

LukaCodes AntiSpam Shield

Block comment spam, brute-force logins and bot registrations with reCAPTCHA v3 or Cloudflare Turnstile. Lightweight, no bloat.

★★★★★
This reCAPTCHA For All plugin’s key advantage is that it blocks page content from being sent to the browser until the user passes the challenge. Unlike most plugins that load the full page and use an overlay to block interaction—allowing bots to scrape content from the source code and overload your server—this plugin ensures the page remains blank for bots. No content is sent from the server until a human is verified, leaving nothing for bots to steal, process, or use to overburden your server.
This plugin provides advanced protection against bots, spam, hackers, fake users, and other types of automated abuse on any selected Page on your site. Utilize invisible reCaptcha V3 (Google) or Turnstile (Cloudflare) to secure your site without disrupting the user experience. Customize the template (Appearance) and messages/language to fit your needs. The plugin also allows you to block visitors from China. Translation ready. Files included: Dutch, English, French, Italian, Portuguese, Spanish, and German. 
 Additionally, it features analytics charts to monitor your site’s protection. 
Installing and getting started with the plugin is quick and easy—even for beginners. Just a few simple steps and you’re up and running!

If you choose Google Recaptcha, after the user click the button, the plugin will send a request to google check that visitor reputation and google sends a immediate response with an score*. 
(*) Cloudflare don’t have the score feature. 
Then, the plugin will allow the user with required score (the score filter rate is up to you) load the page otherwise will block with a forbidden error.
The user browser needs accept cookies and be with javascript enabled. WordPress system also request that, then, it is not a big deal.
This can avoid the bots from stealing your content, consume your bandwidth and overload your server.
