The Analytical Spam Filter 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.

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.

Configuration options include:

Enable Cache Compatibility (requires JavaScript)
Add spam to WordPress queue or block completely
Send diagnostic information to site administrator
Automatically compatible with the Micro Contact Form plugin to block spam messages.
