<p>Are you unsatisfied with your current antispam solution for Contact Form 7? It might be using an ineffective method to combat the specific type of bot attacks you’re facing. Fortunately, I have a solution for you!<br />
Antispam for Contact Form 7 is a simple yet highly effective plugin that protects your mailbox from bot flooding. Say goodbye to tedious configurations and captchas, which often lead to reduced conversions and inconvenience for genuine users. Our plugin utilizes a combination of on-page and off-page bot traps, along with an auto-learning mechanism powered by a statistical “Bayesian” spam filter called B8.<br />
CF7-AntiSpam seamlessly integrates with <a href="https://wordpress.org/plugins/flamingo/" rel="ugc">Flamingo</a> and enhances its functionality. When both plugins are installed, Flamingo gains additional controls, and an extra dashboard widget is enabled.</p>
<h3>SETUP</h3>
<p>Basic – Install and go! No configuration, keys, or registrations are required to activate the antispam protection. In this case, some protections, such as fingerprinting, language checks, and honeypots, will be enabled.<br />
Advanced – For CF7A to properly analyze the email content using its dictionary, it needs to parse the input message field of your form. To notify the antispam to check this field, you’ll need to add a “marker” to each contact form on your website. Simply add ‘flamingo_message: “[your-message]”‘ in the additional settings panel of each contact form you want to secure. This process follows the same method used with Flamingo. While this step may seem tedious, it is required for advanced text statistical analysis. Without it, the B8 filter cannot be enabled.<br />
GeoIP – (Optional) If you need to restrict which countries or languages can email you, you can enable this functionality. To enable GeoIP, you’ll need to agree to the GeoLite2 End User License Agreement and sign up for GeoLite2 Downloadable Databases. This will provide you with the required key to download the database. For detailed instructions, please refer to the dedicated section in the cf7-antispam plugin settings.</p>
<h3>Antispam Available Tests</h3>
<p>✅ Browser Fingerprinting<br />
✅ Language checks (Geo-ip, http headers and browser)<br />
✅ Honeypot<br />
️✅ Honeyform*<br />
✅ Domain Name System Blackhole List (DNSBL)<br />
✅ Blocklists (with automatic ban after N failed attempts, user defined ip exclusion list)<br />
✅ Hidden fields with encrypted unique hash<br />
✅ Time elapsed (with min/max values)<br />
✅ Prohibited words in message/email and user agent<br />
✅ B8 statistical “Bayesian” spam filter<br />
✅ High Entropy / Gibberish checks<br />
✅ Identity protection<br />
✅ Webmail protection</p>
<h3>Extends Flamingo and turns it into a spam manager!</h3>
<p>With this plugin, you can now review emails and train B8 to identify spam and legitimate messages. This feature proves useful, especially during the initial stages when some spam emails may slip through.<br />
Already using Flamingo? Even better! Just remember to add ‘flamingo_message: “[your-message]”‘ to the advanced settings (similar to other Flamingo labels) before activating the plugin. Alternatively, you can explore the advanced options and select “rebuild dictionary.”<br />
Upon activating CF7A, all previously collected emails will be parsed, and B8 will learn and develop its vocabulary. This pre-trained algorithm gives you a head start. How cool is that?<br />
Additional Notes:<br />
– A new column has been added to the right side of the Flamingo inbound page, displaying the level of spaminess for each email.<br />
– If you unban an email on the Flamingo “inbound” page, the corresponding IP will be removed from the blocklist. However, marking an email as spam will not blocklist the IP again.<br />
– Before activating this plugin, please make sure to mark all spam emails as spam in the Flamingo inbound section. This auto-training process will help the B8 algorithm.<br />
– If you receive a spam message, please avoid deleting it from the “ham” section. Instead, place it in the spam section to teach B8 how to differentiate between spam and legitimate messages.</p>
<h3>B8 statistical “Bayesian” Filter</h3>
<p>Originally created by <a href="https://en.wikipedia.org/wiki/Gary_Robinson" rel="nofollow ugc">Gary Robinson</a> <a href="https://www.linuxjournal.com/article/6467" rel="nofollow ugc">b8 is a statistical “Bayesian”</a> spam filter implemented in PHP.<br />
The B8 filter is a foundational example of <strong>Machine Learning (ML)</strong> for text classification, representing an early, yet powerful, statistical approach in Natural Language Processing (NLP). This approach precedes feature-weighting methods like <strong>TF-IDF</strong>, which in turn paved the way for modern deep learning architectures, such as <strong>Transformers</strong> and <strong>GPT</strong>.<br />
The filter tells you whether a text is spam or not, using statistical text analysis. What it does is: you give b8 a text and it returns a value between 0 and 1, saying it’s ham when it’s near 0 and saying it’s spam when it’s near 1. See <a href="https://nasauber.de/opensource/b8/readme.html#how-does-it-work" rel="nofollow ugc">How does it work?</a> for details about this.<br />
To be able to distinguish spam and ham (non-spam), b8 first has to learn some spam and some ham texts. If it makes mistakes when classifying unknown texts or the result is not distinct enough, b8 can be told what the text actually is, getting better with each learned text.<br />
This takes place on your own server without relying on third-party services.<br />
More info: <a href="https://nasauber.de/opensource/b8/" rel="nofollow ugc">nasauber.de</a></p>
<h3>Identity protection</h3>
<p>To fully protect the forms, it may be necessary to enable a couple of additional controls, because bots use the public data of the website to spam on it.<br />
– The first is user related and denies those who are not logged in the possibility of asking (sensitive) information about the user via wp-api and the protection for the xmlrpc exploit wordpress.<br />
– The second one is the WordPress protection that will obfuscate sensitive WordPress and server data, adding some headers in order to enhance security against xss and so on.<br />
Will be hidden the WordPress and WooCommerce version (wp_generator, woo_version), pingback (X-Pingback), server (nginx|apache|…) and php version (X-Powered-By), enabled xss protection headers (X-XSS-Protection), removes rest api link from header (but it will only continue to work if the link is not made public).</p>
<h3>Mailbox Protection (Multiple Send)</h3>
<p>Enhance email security by enabling the “Multiple Send” feature, which prevents consecutive email submissions to the user’s mailbox. This measure is effective in thwarting automated spam attempts and ensures a secure communication environment.</p>
<h3>Security & Privacy: A Local-First Approach</h3>
<p>AntiSpam for Contact Form 7 is built with your security and privacy as the <strong>top priority</strong>. Unlike many modern anti-spam solutions that rely on external cloud services or third-party subscriptions, our plugin is designed to run <strong>entirely on your own WordPress installation</strong>.</p>
<ul>
<li><strong>100% Local Processing:</strong> All anti-spam logic, checks, and data processing are performed directly on your server. <strong>No data is ever sent to, or stored by, any external third-party service</strong> (including ours).</li>
<li><strong>Not a Software as a Service (SaaS):</strong> This plugin is a standalone, self-contained software solution, not an interface to a paid or subscription-based external service. Once installed, it works autonomously.</li>
<li><strong>Enhanced Security:</strong> Since there is <strong>no central server or external API endpoint</strong> to communicate with, your website is immune to potential risks associated with centralized services, such as Single Point of Failure or data breach risks.</li>
</ul>
<p>You retain complete control and ownership over the security of your Contact Form 7 submissions.</p>
<h3>Privacy Notices</h3>
<p>AntiSpam for Contact Form 7 only processes the IP but doesn’t store any personal data directly from the user input. However, it creates a dictionary of spam and ham (non-spam) words in the WordPress database.<br />
This dictionary is built from words found in the submitted messages, meaning it <strong>may contain words that were part of the user’s e-mail message or personal data</strong>. This data is “degenerated,” which means the words might be normalized or altered before being stored.<br />
The sole purpose of this word collecting is to build a dictionary used for local, decentralized spam detection.</p>
<h3>Support</h3>
