Client Chat Filter

This BepInEx mod filters offensive or inappropriate language in Mage Arena’s lobby and in-game chat. It replaces bad words with “bad”, even if they are spaced, obscured, or typed using symbols, leetspeak, or repeated characters.

The plugin integrates seamlessly with the game’s chat system and is optimized for both performance and accuracy, using real-time normalization and detection.

Features

• Obfuscation-Proof Filtering: Detects words with spaces, symbols (e.g., h.e.l.l.o, h e l l o, hhheeeelllooo) and leetspeak (h3ll0, g00dby3)
• Performance Optimized: Handles extremely large word lists with minimal overhead or lag (up to 40 character words currently)
• Invisible Replacement: Replaces only filtered words while leaving the rest of the message untouched
• No External Config Needed: Word list is built-in
