ChatFilterV1
by kuaermdek_
ChatFilterV1 hides chat messages that contain words or phrases on a player-managed block list, including the player's own messages.
What it does
Blocked words and phrases are matched in incoming chat and hidden on the client, so they never appear on screen. The filter also applies to messages the player types. A player manages the list with chatfilter commands to add, remove and list entries, and can view the blocked words over time. Only the client runs the mod, so servers cannot detect it and need nothing installed. It is released under the MIT License and is not open source. Files cover 1.21 – 1.21.8 on Fabric.
Key features

Chatfilter commands
Commands add, remove and list entries on the block list, so the filter can be adjusted without editing files.
Blocked history

MuteIt is a client-side Fabric mod under the Apache License 2.0, not open source, for 1.21.6 – 1.21.8. Spellwords is a server-side MIT License mod, open source, for 1.21.11, so it works on a different side of the connection.
