The Chat Moderation mod is for Forge, and can help server administrators detect words and phrases in chat and replace them with more appropriate messages.
The configuration file allows you to add unlimited words and phrases that should be replaced with censored messages, currently the terms are replaced with ****.
All phrases and words entered into the config for moderation will be checked case-insensitive, so if you enter the term "badword", it will also moderate "baDWoRd" etc.
Simple phrase replacement and more to come to make the functionality more robust. Please comment if you have suggestions for new functionality, and use the issues tracker for any bugs.
