Spam Word Blocker

Spam Word Blocker is a lightweight, WordPress policy-compliant plugin that prevents publishing of any post, page, or custom post type if the content contains unwanted words defined by the admin.

Key Features

• Instant Popup Alert – Shows exactly which blocked words were found
• Works for ALL Post Types – Automatically covers posts, pages, and custom post types
• Lightweight – Only runs during publish events, zero background load
• Server-Side Enforcement – Cannot be bypassed
• Beautiful Admin UI – Clean white and green premium design
• WordPress Policy Compliant – Proper escaping, sanitizing, and nonces
• Case-Insensitive Matching – Smart word-boundary detection

How It Works

1. Admin adds blocked words/phrases (one per line) in plugin settings
2. When user clicks Publish, plugin scans title, content, and excerpt
3. If blocked words found:
   • Instant popup shows which words are blocked
   • Post is saved as draft automatically
   • Admin notice displays after page reload
4. User removes blocked words and republishes successfully

Perfect For

• Content moderation
• Preventing accidental spam content
• Multi-author sites
• Guest post management
• Adult content filtering
