protection from spam for websites. CleanTalk uses protection methods that are invisible to site visitors. Connection to the service eliminates the need for Captcha, questions and answers and other methods of protection, that complicate the exchange of information on the website.</p> <p>The main function of CleanTalk is providing the owners and administrators of websites a reliable tool for protecting your web site against spam and spambots. Invisible for visitors, simple and convenient for administrators, CleanTalk blocks 99,998% of the spam. Thanks to its capabilities, CleanTalk surpasses analogs in: the accuracy of spam detection, the speed of the plugin, provides a report about the work of the service and the availability of additional option SpamFireWall.</p> <h3>How does it work?</h3> <ol> <li>A visitor writes a comment or registers.</li> <li>CleanTalk Anti-Spam plugin sends action parameters in cloud service.</li> <li>The service analyzes the obtained parameters.</li> <li>If it's a visitor, then the comment is published. If it's a spam bot, then CleanTalk blocks this comment or registering.</li> <li>The parameters are written to the log, which you can see in the dashboard.</li> </ol> <p>The cost of the license for one website is $12 per year.</p> <p>The full list of supported CMS with installation instructions is here: <a href="/help/install">https://cleantalk.org/help/install</a></p> <p>Akismet vs CleanTalk comparison: <a href="/help/cleantalk-vs-akismet">https://cleantalk.org/help/cleantalk-vs-akismet</a></p> <p> </p> <h2 style="text-align: center;"><a id="45_day_log"></a>45 Day Log</h2> <p> </p> <p>Every CleanTalk customer has <strong>7 Day Log</strong> by default. It is possible to extend its duration by activating Extra Package for advanced options. It can be done here: <a href="/help/extra-package">https://cleantalk.org/help/extra-package</a></p> <p>Your Anti-Spam Log stores every blocked and approved record received from your website. It helps to know the full activity of spambots and real visitors 24/7. It's a powerful tool to monitor your website. Anti-Spam Log page: <a class="text-break" href="/my/show_requests?int=week">https://cleantalk.org/my/show_requests?int=week</a></p> <p>45 days Log is included in the <a href="extra-package">Extra package</a>, which includes:</p> <ul> <li>Keep a history of spam attacks 45 days.</li> <li>Filter posts by stop-word list.</li> <li>Spam filter by country.</li> <li>Editing the server response.</li> <li>Website Access Delegation</li> <li>Website Event Notifications</li> <li>CleanTalk dashboard settings templates</li> </ul> <p> </p> <p> </p> <h2 style="text-align: center;"><a id="country_blocking"></a>Blocking Visitors by Country</h2> <p> </p> <p><img style="float: right; width: auto; height: 150px;" src="https://s3.amazonaws.com/cleantalk-screenshots/Introduction/6mHQ7Y9.webp" alt="globe" /></p> <p>CleanTalk provides 2 different types of blocking users by country:</p> <ul> <li>Anti-Spam</li> <li>SpamFireWall</li> </ul> <h3>Anti-Spam</h3> <p>Blocking by country using Anti-Spam filtration service allows you to block only comments/registrations on the site from users from certain countries. The site will be available for visitors and they can view it, but will not be able to leave a comment.</p> <h3>How does it work?</h3> <ul> <li>At the moment when the visitor sends a comment or is logged, the form parameters are sent to the server CleanTalk.</li> <li>The IP address of the visitor is checked for a ban.</li> <li>If the IP address belongs to the country for which the lock is enabled, the visitor will receive a notification.</li> </ul> <p>This option is useful in cases of protection from manual spam and enhances protection. If your website isn't aimed at an international audience, and you don't expect comments/users from other countries. For example, your website is about fishing in Ireland, then there is no need for comments from Asia or Africa and you can block a comment from spam active countries.</p> <h3>SpamFireWall</h3> <p>Blocking traffic by country using Spam FireWall allows you to partially block access to the site for the IP addresses of specific countries. All visitors from the blocked country will be given a special page, while ordinary users will be able to go through it and be able to view the site, comment, and register, but bots will not be able to go through this page. This option is useful because it can significantly reduce the load on the site, since all GET requests will be blocked and the site will not execute scripts for these requests, the blocking page almost does not consume any server resources. It can be used to block brute force attacks, vulnerability scanners, various bots, as well as to temporarily block traffic in some types of DoS attacks, when attackers send thousands of HTTP requests to the site, reduce the likelihood of hacking the site.</p> <p>You can enable the option in the CleanTalk Dashboard  -> Tools -> Personal list<em>s</em>  or use the link <a href="/my/show_private">https://cleantalk.org/my/show_private</a></p> <p> </p> <p><img src="https://cleantalk-screenshots.s3.amazonaws.com/articles/introduction/Country_Blacklist_en.webp" alt="Personal Blacklists" width="674" height="336" /></p> <p>Personal Blacklist Manual: <a title="Personal Blacklist Manual" href="/help/blacklist-usage">https://cleantalk.org/help/blacklist-usage</a></p> <p>Blocking by country is included in the <a href="extra-package">Extra package</a>, which includes:</p> <ul> <li>Keep a history of spam attacks 45 days.</li> <li>Filter posts by stop-word list.</li> <li>Spam filter by country.</li> <li>Editing the server response.</li> <li>Website Access Delegation</li> <li>Website Event Notifications</li> <li>CleanTalk dashboard settings templates</li> </ul> <p> </p> <p> </p> <h2 style="text-align: center;"><a id="stopwords_blocking"></a>Blocking by Stop-Words</h2> <p> </p> <p><img style="float: left; width: auto; height: 150px;" src="https://s3.amazonaws.com/cleantalk-screenshots/Introduction/MRiCNrc.webp" alt="dialog" />You can block comments containing "stop words" to enhance spam filtering and blocking messages containing obscene words. You can add a certain word or phrase.</p> <h3>How does it work?</h3> <p>For enabling the option, go to your <a href="/my/?cp_mode=antispam">CleanTalk Dashboard</a> —> choose any website and press "Settings" under its name, check the option "Enable Message Filtration Using Stop-Words" and click "Save". Comments containing "Stop-Words" will not be published and will be sent to manual moderation.</p> <p>Use this guide to get more details about the feature: <a href="/help/stop-word">https://cleantalk.org/help/stop-word</a></p> <p><img src="https://cleantalk-screenshots.s3.amazonaws.com/articles/introduction/Stop_Word_Feature_en.webp" alt="Website options" width="968" height="530" /></p> <p>Personal Blacklist Manual: <a title="Personal Blacklist Manual" href="/help/blacklist-usage">https://cleantalk.org/help/blacklist-usage</a></p> <p> Stop words dictionary is included in the <a href="extra-package">Extra package</a>, which includes:</p> <ul> <li>Keep a history of spam attacks for 45 days.</li> <li>Filter posts by stop-word list.</li> <li>Spam filter by country.</li> <li>Editing the server response.</li> <li>Website Access Delegation</li> <li>Website Event Notifications</li> <li>CleanTalk dashboard settings templates</li> </ul> <p> </p> <p> </p> <h2 style="text-align: center;"><a id="language_blocking"></a>Blocking by Language</h2> <p> </p> <p>Spam spreads not only in English. Many spam messages are written in Chinese, Arabic, Japanese or Korean languages.</p> <p>If your website isn't aimed for an international audience and you don't expect comments/users in other languages. For example, your website is about fishing in Ireland and you don't want to have comments in the Chinese language.</p> <p>We added a new filter to block comments/messages by languages.
