Cassetu’s Better Chat Control – CBCC

CBCC

Cassetu’s Better Chat Control (CBCC) is a client-side Fabric mod for Minecraft 1.21.11 that filters toxic messages, spam, excessive caps, and links from chat, replacing them with a placeholder you can click if you want to reveal the original message.

Toxicity Filter

Checks every incoming chat message against a local wordlist stored in config/cbcc/wordlist.json. No external services or API calls. Supports whole-word matching, common leetspeak substitutions (like 4 → a or 3 → e), and catches words split across multiple messages to help prevent simple bypasses.

Link Filter

Collapses messages containing URLs, helping reduce phishing links and unwanted advertising in chat.

Caps Filter

Collapses messages that are mostly uppercase once they pass a configurable length and percentage threshold. Short messages like GG are ignored.

Spam Filter

Tracks recent messages from each sender in a rolling time window. Repeated messages beyond a configurable threshold are collapsed to reduce chat spam.

Click to Reveal

Collapsed messages appear as [Message Hidden (reason) - Click to View]. Clicking the message restores the original chat message locally. Nothing is deleted—it’s only hidden until you choose to view it.

Config Overlay

Open with [ (rebindable). A lightweight HUD lets you toggle filters without opening a menu or pausing the game. Changes are saved to config/cbcc.json immediately and take effect without restarting.

Commands

• /cbcc reveal <id> – Used internally by click-to-reveal messages.
• /cbcc reload – Reloads the wordlist from disk without restarting the game.

Key Bindings

All keybinds are fully rebindable:

• Open Config ([)
• Move Up
• Move Down
• Toggle Selected (Enter)
