<p>This is fork of successful Anti-spam plugin v5.5 written by webvitalii, for more info visit <a href="https://github.com/kudlav/anti-spam/" rel="nofollow ugc">GitHub Fork</a>.<br />
From version 5.6 maintained by kudlav.</p>
<ul>

</ul>
<p>Anti-spam Reloaded plugin blocks 100% of automatic spam messages in comments section and also blocks all trackbacks.No captcha required.</p>
<p>Plugin is simple and easy to use: just install it and it just works.</p>
<p>Blocked comments can be stored in the Spam area and converted to regular comments if needed.</p>
<p>Anti-spam Reloaded plugin is GDPR compliant and does not store any other user data except of the behaviour mentioned above.</p>
<p><strong>Plugin blocks spam only in comments section.</strong>.<br />
Plugin does not block manual spam (submitted by spammers manually via browser).</p>
<h3>Compatibility</h3>
<p>All modern browsers and IE11+ are supported.<br />
Anti-spam Reloaded plugin works with disabled JavaScript. Users with disabled JavaScript should manually fill current year before submitting the comment.</p>
<p>Server compatibility:</p>
<ul>
<li>WordPress 3.3 – 6.5</li>
<li>PHP 5.6 – 8.2</li>
<li>Doesn’t use jQuery</li>
</ul>
<p>Plugin is incompatible with:</p>
<ul>
<li>Disqus</li>
<li>Jetpack Comments</li>
<li>AJAX Comment Form</li>
<li>bbPress</li>
</ul>
<p>If site has caching plugin enabled and cache is not cleared or if theme does not use ‘comment_form’ action<br />
and there is no plugin inputs in comments form – plugin tries to add hidden fields automatically using JavaScript.</p>
<h3>How does it work?</h3>
<p>The blocking algorithm is based on 2 methods: ‘invisible js-captcha’ and ‘invisible input trap’ (aka honeypot technique).</p>
<h4>‘invisible js-captcha’</h4>
<p>The ‘invisible js-captcha’ method is based on fact that bots does not have JavaScript on their user-agents.<br />
Extra hidden field is added to comments form.<br />
It is the question about the current year.<br />
If the user visits site, than this field is answered automatically with JavaScript, is hidden by JavaScript and CSS and invisible for the user.<br />
If the spammer will fill year-field incorrectly – the comment will be blocked because it is spam.</p>
<h4>‘invisible input trap’</h4>
<p>The ‘invisible input trap’ method is based on fact that almost all the bots will fill inputs with name ’email’ or ‘url’.<br />
Extra hidden field is added to comments form.<br />
This field is hidden for the user and user will not fill it.<br />
But this field is visible for the spammer.<br />
If the spammer will fill this trap-field with anything – the comment will be blocked because it is spam.</p>
