2b2t Adblocker
by sarfe_
2b2t Adblocker filters advertisement messages out of the chat window, using a configurable list of regular expressions.
What it does
Chat messages matching a pattern are hidden on the client, which suits players on 2b2t and other servers where ad spam fills the chat. The block list is a set of regular expressions that can be edited in the configuration, and a message can also be ignored with a right click so that similar lines stop appearing. Configuration is reached through Mod Menu, and the mod needs Cloth Config API for its settings screen.
The mod is client-side only, so servers run without it and players are the only ones who install it. It is open source under the GNU General Public License v3.0 only, and the source code is publicly available. Files are published for Fabric only, covering game versions 1.21 – 1.21.5, with 3.0 for 1.21.5 as the latest file released on 2025-06-16.
Key features
Chat spam filter
Messages that match a configured pattern are removed from the chat before they can be read.
Configurable block patterns
Each entry in the block list is a regular expression, so the filter can be tuned to a server's own spam wording.
Right-click ignore
A message can be ignored with a right click, adding it to the filter without editing the configuration file.
Settings through Mod Menu
Options are gathered in one screen opened from the Mod Menu list, with Cloth Config API drawing the controls.

Use cases
Ad-heavy servers
Players on servers where advertisements flood the chat can hide repeated promotional lines without leaving the game.
Who it’s for: Players on 2b2t and other public servers that suffer from advertisement spam in chat. Server owners have no need for it, since the mod acts only on the player's own client.
