<p>The <strong>Analytical Spam Filter</strong> plugin for WordPress blocks comment, trackback, and pingback spam. It uses multiple spam detection methods without challenging the user with obstacles such as captchas, math problems, etc. and it does not rely on external services or APIs. This is a low overhead plugin that begins blocking spam as soon as it is activated. It is compatible with caching plugins as long as the user has JavaScript enabled. The plugin blocks spam submitted through the default WordPress comment form only.</p>
<p>Logic is used to identify spam comment submissions. No user interaction is required. The spam blocking mechanisms work transparently behind the scenes. Most visitors will require longer than a few seconds to read a post and add a meaningful comment so any comments submitted within a short time threshold are identified as spam. Comments containing a large number of links are flagged as spam. The plugin uses an encrypted code and a honeypot to filter robotic submissions. All field names added by the plugin are randomized to prevent detection based on a source code signatures.</p>
<p>Configuration options include:</p>
<ul>
<li>Enable Cache Compatibility (requires JavaScript)</li>
<li>Add spam to WordPress queue or block completely</li>
<li>Send diagnostic information to site administrator</li>
<li>Automatically compatible with the <strong>Micro Contact Form</strong> plugin to block spam messages.</li>
</ul>

<li>Automatically block repeated spam from IP</li>
<li>Automatically block repeated spam based on content</li>

Antispam Bee


Using it since years and had no spam in my blog ever. Simple, clean, works.


Best Antispam Plugin


I've tested this plugin and seems to working very well. Most spam comments are gone, some of them (just a little) are able to avoid spam filters.



There is something need to be fixed and I'm already posted in support forum. I hope that it will be fixed soon.


Very good spam filter plugin.


Works quite well without calling out to a remote service, and doesn't require your visitors to be using JavaScript. (Seriously, I posted a test comment using Dillo and it showed up in the moderation queue!) No need to deal with API keys or licensing.



There are some optional tactics that will call a remote service for things like language identification, but so far it's doing the job fine without them!



The only problem I've had with it is that it only acts on comments, not on other features like contact forms.


Privacy-friendly spam filter


Simple to set up and use. Catches all the spam and deletes it before I get a chance to see it. Might miss one or two pieces a week, but that's still better than JetPack and it preserves my users' privacy.


Works better than JetPack

Sophisticated antispam plugin for effective daily comment and trackback spam-fighting. Built with data protection and privacy in mind.
