Analytical Spam Filter Plugin for WordPress
The Analytical Spam Filter plugin for WordPress effectively blocks comment, trackback, and pingback spam. It employs multiple spam detection methods without presenting obstacles like captchas or math problems to users, and it does not rely on external services or APIs. This low-overhead plugin begins blocking spam as soon as it is activated and is compatible with caching plugins, provided that JavaScript is enabled. The plugin works specifically for blocking spam submitted through the default WordPress comment form.
The plugin uses logic to identify spam comments, with no user interaction required. The spam-blocking mechanisms operate transparently in the background. Most visitors will take longer than a few seconds to read a post and add a meaningful comment, so any comments submitted within a short time threshold are flagged as spam. Comments containing an excessive number of links are also marked as spam. Additionally, the plugin uses an encrypted code and a honeypot to filter out robotic submissions. All field names added by the plugin are randomized to prevent detection based on source code signatures.
