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>

Anti-spam, Spam protection, ReCaptcha for all forms and GDPR-compliant


Blocked hundreds of spam WooCommerce orders, and the plugin continues to be actively monitored and improved. I'm sure it will continue to get even better. Great work.


Excellent


The developer is really motivated to get this plugin going. Nice guy.



And the plugin helps catching spam without violating GDPR. Great for german or EU-sites.



Thanks a lot for this plugin.


Works like a charm and great developer-support
