ChatBlocker — Smart Local Player Ban in Chat!

ChatBlocker is a lightweight, fully client-side mod for Fabric (Minecraft 1.21–1.21.4), designed to permanently ban spam, flooding, and toxic players from your chat.

The mod runs exclusively on your computer, meaning you can use it on absolutely any public server. The server won't even know you have the mod, and your chat will be clean and comfortable!


Main Features

  • ** One-Click Blocking:** Spotted a toxic player? Simply click on their message directly in the chat, and they'll instantly be added to your personal blocklist.
  • ** Absolute Locality:** The mod doesn't send any requests to the server. The blocking occurs visually only on your PC. * ** Nice Sounds:** Each successful block or unblock is accompanied by a vanilla interface sound effect.

User-Friendly Built-in GUI

Forget complicated third-party libraries! The mod has a built-in settings menu powered by the pure Minecraft engine. Simply join a world or server and press the English key O on your keyboard:

  • ** "Full Hiding" Toggle:**
  • ON: Messages from blocked players disappear from the chat without a trace (no blank lines or spaces).
  • OFF: Messages are replaced with a neat gray box. Clicking it allows you to read the hidden text one-time.
  • ** "Mod Sounds" Toggle:** Allows you to easily enable or disable sound clicks when banning.
  • ** Interactive Player List:** View a list of all blocked players directly from the menu, with convenient unblock crosses automatically displayed in the chat.

Mod Commands

All commands are executed locally on your client:

  • `/blockplayer ` — manually block a player by nickname.
  • `/unblockplayer ` — unblock a player.
  • /blocklist — display a list of all blocked players in the chat with interactive buttons for quick removal [❌] with a mouse click.

Dependencies

This mod requires only the Fabric API.
