Tiny Comment Spam Blocker

Описание

Tiny Comment Spam Blocker is a lightweight yet powerful plugin designed to protect your WordPress comments from spam. It employs five different techniques to detect and block unwanted comments:

1. Nonce Verification – Ensures that the comment form submission is genuine.
2. Submission Time Check – Blocks comments submitted too quickly to prevent bots.
3. Honeypot Field – Hidden field that traps automated spam bots.
4. User Agent Validation – Detects suspicious User-Agent strings and blocks them.
5. Forbidden Word Filtering – Blocks submissions containing words or phrases from a configurable list within the comment body, email address, or IP address.

These filters are applied in order: if a comment passes the first check, it proceeds to the second, and so on, until all checks are applied or the comment is blocked.

Additional features:

• Option to log detected spam in a local log file (up to 1.0 MB).
• Optional email notifications when spam is detected.
• Easy settings page in the WordPress admin panel.

Settings

The plugin provides the following settings in the WordPress admin panel:

• Enable Spam Protection – Toggle the spam protection on or off. When disabled, all anti-spam checks are skipped.
• Save Spam Detection Log – Enable or disable logging of detected spam. Logs are saved in a local file up to 1.0 MB within the WordPress uploads directory.
• Notification Email Address – Enter an email address to receive notifications when spam is detected. Leave blank to disable email notifications.
• Minimum Submission Time (seconds) – Set the minimum allowed time between loading the comment form and submitting a comment. Comments submitted faster than this threshold are considered spam.
• Forbidden Words List – Enter one forbidden word, phrase, or IP address per line. Submissions containing these entries in the comment body, email address, or IP address will be blocked. Case is insensitive.
