Custom Message Blocker

The mod included in this project is a little mod I've been working on that adds the ability to not show certain chat messages. They can be messages which contain a word you don't want to see, or an EXACT word you don't want to see.

Custom Message Blocker

Tired of certain words or phrases cluttering your chat? Custom Message Blocker lets you automatically hide certain chat messages containing (or exactly matching) phrases you don't want to see.

Features

Custom filter rules — Add as many blocked phrases as you want
Two modes:
- CONTAINS — blocks any message that includes your phrase anywhere
- EXACT — blocks only messages where your phrase is the actual message sent
On/off switch — disable the entire mod if you wish.
Optional alerts — get a subtle action bar notification when a message is blocked, so you know filtering is working
In-game config GUI — manage all your rules visually, no config file editing required
Keybind & command support — open settings with \ (rebindable) or /blockerconfig
100% client-side — works on any server

How to Use

Press \ (default keybind) or run /blockerconfig to open the GUI
Type a phrase you want blocked and choose CONTAINS or EXACT mode
Click + Add Rule
Done!
