SP Adblock
by Avro170
SP Adblock is a client-side Fabric mod that filters chat messages, including advertising posted on SPWorlds SP servers, and mutes individual players.
What it does
The mod works quietly in the background and removes unwanted messages from the chat feed. Filtering runs on the client, so it applies to whatever server a player joins, and the mod is designed for SPWorlds SP5 servers. Players can build their own blocklist of words with simple in-game commands, and they can mute a player by username.
Two default local filter lists ship with the mod, and each list can be switched on or off in the Mod Menu screen. Custom filter lists are supported: a player drops a file of keywords into the config folder and it appears in the interface automatically. Chat parsing separates the username from the message content, so a prefix or a nickname format does not cause false positives. Muted players are stored by both username and UUID, so a mute survives a name change.
Filter lists are kept locally: copies of the lists are fetched from GitHub and stored on the player's machine. Mod Menu is an optional dependency that provides the configuration screen; the mod works without it through its config files. The code is open source under the GNU General Public License v3.0 only, and the Fabric build is published for 1.21 – 1.21.11.
Key features
Chat ad blocking
Advertising messages from SPWorlds SP servers are removed from the chat feed before they clutter the screen.
Personal word blocklist
A blocklist of words is managed with in-game commands, so only the messages a player wants gone are hidden.
Persistent player muting
A muted player is recorded by UUID as well as username, which keeps the mute in place after a name change.
Toggleable filter lists
Two default local lists and any custom lists can be enabled or disabled in the Mod Menu interface.
Custom filter lists
A keyword file dropped into the config folder appears in the interface as a new list that can be toggled.
Chat format parsing
Usernames are separated from message text, so custom chat formats with a prefix or nickname are read correctly.
