Glyph Shield is a plugin that helps website administrators control their comment sections by preventing submissions containing unwanted characters, words, or patterns. It is for site owners who want to reduce spam and maintain cleaner discussions with minimal setup.

• Character Blocking: Specify individual letters, numbers, or symbols (like certain Unicode characters) that will cause a comment to be rejected if used.
• Word and Pattern Filtering: Create lists of banned words or regular expression patterns to catch spam phrases and unwanted terminology automatically.
• Customizable Error Messages: Set the message displayed to users when their comment is blocked, allowing for clear communication of moderation policies.
• Simple Configuration: Manage all blocking rules from a single settings page within the admin area, requiring no advanced technical knowledge to implement.
• Lightweight Operation: Works by filtering comments before they are posted, adding negligible overhead to site performance.
