AI-Powered Discord Moderation System for Large Communities

Introducing a production-grade Discord automoderation system designed for large communities, agencies, and SaaS resale. This comprehensive solution goes far beyond basic keyword filtering to provide robust protection for your Discord server with advanced detection capabilities.

Advanced Text Moderation Engine

Our system features sophisticated text analysis that intelligently deobfuscates and reconstructs harmful language, making it extremely difficult to bypass. The text filter includes:

• Unicode confusable mapping
• Leetspeak and digit replacement detection
• Diacritic stripping and zero-width character removal
• Phonetic simplification
• Separator removal (converting s.l-u_r to slur)
• Multi-character visual fixes (recognising rn as m)
• Repetition normalisation (transforming "cooool" to "cool")
• Star/wildcard bypass detection (f*g, f**-g*ot)

Content is analysed across multiple categories, including slurs, hate speech, and custom-banned terms, with normalised pattern matching ensuring comprehensive protection.

Machine Learning-Powered Image Moderation

Unlike basic moderation systems that only check filenames, our solution analyses the actual content of images using:

• TensorFlow NSFWJS technology
• Custom gore-detection heuristics
• Tesseract OCR for text extraction from images
• Intelligent quality assessment

The system reliably detects inappropriate content, including pornography, hentai, suggestive material, gore/violence, and even slurs or hate text embedded within images. Safety features include domain allowlisting, size limitations, fetch timeouts, auto-downscaling, concurrency controls, and idle model disposal to maintain optimal performance.

Anti-Spam Protection

The anti-spam engine employs a sliding window approach with strict accuracy to:

• Detect 5+ messages sent in less than 2 seconds
• Capture sample messages for review
• Bulk delete spam content
• Automatically time out offenders for 1 hour
• Prevent memory buffer buildup

This system remains reliable even during rapid spam raids, protecting your community when it matters most.

Anti-Grief and Anti-Nuke Protection

To prevent server compromise, the system monitors all ban and kick actions. If anyone performs 10 or more bans/kicks (or a combination) within 5 seconds, the system:

• Automatically times out the executor for 72 hours
• Sends alerts to staff
• Prevents catastrophic server damage from compromised accounts or rogue moderators

Comprehensive Configuration and Logging

Each server benefits from persistent configuration options stored safely in JSON with batched writes. Administrators can toggle automod features, configure image moderation, set exempt roles, designate log channels, and more.

The full logging system records moderation actions with detailed information, including: - Moderation type - User identification - Channel and message details - Timestamps and reasons

All logs are accessible via commands and designated log channels, with content, matches, attachments, and message links preserved for reference.

Professional Engineering

Built with a modular ES Module architecture, this solution incorporates: - Graceful exit handling - Memory management - Concurrency control - Exception handling - Resource disposal timers

The system is implemented with slash commands that register automatically for each guild, providing intuitive access to all features through Discord's native interface.

This isn't merely a basic moderation bot – it's a comprehensive, production-ready platform that combines machine learning, optical character recognition, and advanced text normalisation to deliver superior protection for Discord communities.
