Neutrope Inc.

<p>Neutrope Quiet Shield adds lightweight spam and unsolicited-sales filtering to<br />
Contact Form 7 submissions. The idea is simple: let spam and cold sales<br />
mail be received quietly without disturbing the people running the site.</p>
<p>Each submission is scored against a small set of checks you control:</p>
<ul>
<li>Japanese character ratio: flag messages with too little Japanese text.</li>
<li>URL limit: flag messages that contain more links than you allow.</li>
<li>Submission speed: flag forms submitted suspiciously fast after they were<br />
shown. The timing value is signed so it cannot be tampered with.</li>
<li>Repeat submissions: flag three or more submissions from the same visitor<br />
within five minutes.</li>
<li>NG words: flag messages containing any keyword from your own list.</li>
</ul>
<p>When a submission is flagged you choose what happens with Quiet Mode:</p>
<ul>
<li>Quiet Mode on (default): the visitor sees the normal success message, but<br />
no mail is sent. The reason is written to the log.</li>
<li>Quiet Mode off: the submission is stopped with the standard Contact Form<br />
7 error message.</li>
</ul>
<p>The plugin is deliberately small. It makes no external network requests,<br />
creates no database tables, and shows no ads or upsells. Configuration is<br />
stored in a single option, and the log keeps only decision metadata plus a<br />
short, salted IP hash. Message bodies, e-mail addresses and names are never<br />
stored.</p>
<p>If Contact Form 7 is not active, the plugin still activates safely and<br />
shows an admin notice instead of causing an error.</p>
<p>This plugin is an independent add-on and is not affiliated with or endorsed<br />
by the authors of Contact Form 7.</p>
<h3>Features</h3>
<ul>
<li>Five independent checks, each configurable from one settings page.</li>
<li>Quiet Mode to silently drop flagged mail or stop it with an error.</li>
<li>Dashboard with today’s passed and blocked counts and a recent activity<br />
log.</li>
<li>Tamper-evident submission-speed measurement using a signed field.</li>
<li>IP addresses are hashed, never stored in raw form.</li>
<li>No external requests, no tracking, no database tables, no ads.</li>
<li>GPL-2.0-or-later. The full license text is bundled in the LICENSE file.</li>

<h3>External Services</h3>
<p>This plugin relies on external services to provide spam detection and geolocation features. Below is detailed information about each service:</p>
<h4>SpamBanana API (api.spambanana.com)</h4>
<p><strong>What it does:</strong> Analyzes comments using Machine Learning (Logistic Regression + TF-IDF) to detect spam.</p>
<p><strong>When data is sent:</strong> Every time a comment is submitted on your WordPress site (unless the user is logged in and you’ve disabled checking for logged-in users).</p>
<p><strong>What data is sent:</strong><br />

* Comment author name<br />
* Comment author email<br />
* Comment author IP address<br />
* Comment author website URL (if provided)<br />

<p><strong>Why it’s needed:</strong> WordPress servers have limited resources. By processing spam detection on our dedicated ML servers, we:<br />
* Reduce load on your WordPress server<br />
* Provide faster spam detection<br />
* Use advanced Machine Learning models that would be too resource-intensive to run locally<br />
* Continuously improve accuracy through centralized learning from millions of comments<br />
* Reduce AI costs for users by sharing infrastructure</p>
<p><strong>Data retention:</strong> Comment data is stored temporarily for analysis and learning. Spam detection results are kept to improve the ML model accuracy over time.</p>

<p><strong>What data is sent:</strong><br />
* Visitor’s IP address only</p>
<p><strong>Why it’s needed:</strong> To identify the country of origin for comments, allowing you to block spam from specific countries if desired.</p>
