How the Protection Works in Action

User Creates Content
A content creator (author, editor, or contributor) writes a post or page using the WordPress editor.
Publish Button Clicked
When the user clicks the "Publish" button, the plugin instantly scans the content for any blocked words.
Instant Popup Alert Appears
If blocked words are detected, a professional popup immediately appears showing exactly which words were found. The post is automatically saved as a draft instead of publishing.
User Edits and Republishes
The content creator sees the specific blocked words, edits the content to remove them, and can then successfully publish their post.
Live protection in action: Instant popup alert showing which blocked words were detected, with clear instructions to edit the content before publishing
Complete Protection Guarantee
The plugin provides double protection: First, an instant popup alert warns the user immediately. Second, server-side validation ensures the content cannot be published even if someone tries to bypass the popup. Your website is completely protected!
After the popup appears, an admin notice also displays on the next page load, ensuring the message isn't missed if the popup is accidentally closed.

Important Note
While Spam Word Blocker is highly effective at preventing specific words from being published, it's designed as a content moderation aid, not a complete content review system. We recommend combining the plugin with other quality control measures for best results.
The plugin is provided "as is" under the GPL v2 license. While we strive for bug-free operation, no software is perfect. Always maintain regular backups of your WordPress website and test new plugins on a staging site when possible.
