# AI Agent Blocking

> Comprehensive guide to AI agent blocking and management in the LLMTAG plugin

## AI Agent Blocking Overview

The LLMTAG plugin maintains a comprehensive database of 60+ known AI agents and crawlers, allowing you to selectively block or allow them based on your content protection needs.

## How AI Agent Blocking Works

### Blocking Mechanism

The plugin uses multiple layers of protection to block AI agents:

<Steps>
  <Step title="User-Agent Detection">
    Analyze incoming requests to identify AI agents by their user-agent strings.
  </Step>

  <Step title="Database Lookup">
    Check the AI agent database to determine if the agent should be blocked.
  </Step>

  <Step title="Policy Application">
    Apply your configured blocking rules and exceptions.
  </Step>

  <Step title="Request Blocking">
    Block the request before it reaches your content, returning a 403 Forbidden response.
  </Step>

  <Step title="Logging and Analytics">
    Log the blocked request for monitoring and analysis.
  </Step>
</Steps>

### Blocking Methods

<Tabs>
  <Tab title="Server-Level Blocking">
    **Method:** .htaccess rules and server configuration
    **Advantages:** Fast, efficient, works at the server level
    **Best for:** Most websites, high-traffic sites
  </Tab>

  <Tab title="Application-Level Blocking">
    **Method:** WordPress plugin hooks and filters
    **Advantages:** More flexible, easier to configure
