Implement Secure GraphQL Rate Limiting in Laravel

Design a sophisticated GraphQL rate limiting middleware for a SaaS API using Laravel that dynamically adjusts throttling based on user subscription tier. Create a system that tracks API consumption in real-time, implements sliding window rate limiting, and provides granular control over different endpoint access. Include mechanisms for generating detailed consumption reports, handling burst requests, and automatically blocking IPs that exceed predefined thresholds. Provide a comprehensive implementation that integrates with Laravel's authentication system and supports multiple rate limit strategies.
