<p>Tiny Comment Spam Blocker is a lightweight yet powerful plugin designed to protect your WordPress comments from spam. It employs five different techniques to detect and block unwanted comments:</p>
<ol>
<li><strong>Nonce Verification</strong> – Ensures that the comment form submission is genuine.</li>
<li><strong>Submission Time Check</strong> – Blocks comments submitted too quickly to prevent bots.</li>
<li><strong>Honeypot Field</strong> – Hidden field that traps automated spam bots.</li>
<li><strong>User Agent Validation</strong> – Detects suspicious User-Agent strings and blocks them.</li>
<li><strong>Forbidden Word Filtering</strong> – Blocks submissions containing words or phrases from a configurable list within the <strong>comment body, email address, or IP address.</strong></li>
<li><strong>JavaScript-Based Human Interaction Detection</strong> – Sets a verification token when mouse movement, scrolling, or touch interaction is detected.</li>
<li><strong>(Option) Block Non-Japanese Comments</strong> – Blocks comments that do not contain Japanese characters (Hiragana, Katakana, or Han/Kanji), primarily targeting machine-translated or foreign spam.</li>
</ol>
<p>These filters are applied in order: if a comment passes the first check, it proceeds to the second, and so on, until all checks are applied or the comment is blocked.</p>
<p>Additional features:</p>
<ul>
<li>Option to log detected spam in a local log file (up to 1.0 MB).</li>
<li>Optional email notifications when spam is detected.</li>
<li>Easy settings page in the WordPress admin panel.</li>
</ul>
<h3>Settings</h3>
<p>The plugin provides the following settings in the WordPress admin panel:</p>
<ul>
<li><strong>Enable Spam Protection</strong> – Toggle the spam protection on or off. When disabled, all anti-spam checks are skipped.</li>
<li><strong>Save Spam Detection Log</strong> – Enable or disable logging of detected spam. Logs are saved in a local file up to 1.0 MB within the WordPress uploads directory.</li>
<li><strong>Notification Email Address</strong> – Enter an email address to receive notifications when spam is detected. Leave blank to disable email notifications.</li>
<li><strong>Minimum Submission Time (seconds)</strong> – Set the minimum allowed time between loading the comment form and submitting a comment. Comments submitted faster than this threshold are considered spam.</li>
<li><strong>Forbidden Words List</strong> – Enter one forbidden word, phrase, or IP address per line. Submissions containing these entries in the comment body, <strong>email address</strong>, or <strong>IP address</strong> will be blocked. <strong>Case is insensitive.</strong>
<ul>
<li><strong>Example:</strong><br />
viagra<br />
online pharmacy<br />
spam@email.com<br />
164.138.205.72</li>
</ul>
</li>
<li><strong>Block No Japanese Comments</strong> – If enabled, this becomes the final check: Comments that contain Japanese characters (Hiragana, Katakana, or Kanji) will be automatically accepted after passing other security checks. <strong>Comments without Japanese characters will be blocked.</strong></li>
</ul>

<p>Honeypot Anti-Spam es un plugin antispam para WordPress que te permite proteger los formularios de comentarios mediante la técnica honeypot.</p>
<p>El uso de la técnica honeypot implica que, si instalas Honeypot Anti-Spam, no necesitarás incluir un molesto captcha en tu WordPress. El motivo es que honeypot es completamente invisible para el visitante.</p>
<p>La técnica antispam honeypot consiste en un campo oculto que se introduce mediante javascript en los formularios. Un visitante legítimo nunca llega a ver este campo ni, por lo tanto, a rellenarlo. En cambio, los spam bots lo detectan y lo rellenan, por lo que el comentario o envío se clasifica como SPAM de manera inmediata.</p>
<p>Honeypot Anti-Spam NO tiene opciones ni configuración. Para hacer que empiece a funcionar solo tienes que instalar y activar. Nada más.</p>
<h3>Instalación</h3>
<ol>
<li>Instalar y activar el plugin desde el dahsboard de WordPress.</li>
<li>¡Ya está! No tienes que hacer nada más.</li>
</ol>
<h3>Preguntas frecuentes</h3>
<h4>¿Es efectiva la técnica honeypot para el spam?</h4>
<p>Sí, es efectiva contra bots, aunque NO funciona contra el spam manual. De todas formas, en el 99,99% de los casos, el spam se realiza de forma automática mediante bots.</p>
<h4>¿Afectará en algo a mi WordPress?</h4>
<p>No, el sistema es completamente automático y no afecta al funcionamiento normal de WordPress: es transparente.<br />
En casos muy raros, algún plugin puede dar problemas con el javascript usado para insertar el campo honeypot, pero ocurre muy pocas veces.</p>
<h4>¿Puedo usar Honeypot Anti-Spam con Disqus o wpDisquz?</h4>
<p>No, Honeypot Anti-Spam no es compatible con otros sistemas de comentarios que no sean los de WordPress.</p>
