Cleanse
by necauqua
Cleanse is a Forge client mod that filters chat messages shortly after a world opens, to stop login spam from large modpacks.
What it does
Right after a world loads, some modpacks flood the chat with messages. Cleanse hides messages that are not from vanilla during a short window that starts when the world opens. The window lasts one second by default, and its length can be raised in the config file for packs that keep sending messages for longer.
The mod works only on the client, so players install it and servers do not need it. It is open source under the MIT License, and the source code, issue tracker and wiki are public. Files are published for Forge only, across 29 release versions 1.12 – 1.19.3, with 1.19-8.0.0.0 for 1.19.3 as the latest file, dated 2023-01-22.
The author notes that Cleanse is a small utility aimed at one problem, and that partial spam can still appear because some messages are sent after the window closes. Raising the configured time is the only adjustment the mod offers.
Key features
Chat filtering after load
Non-vanilla chat lines are hidden for a short period after the world opens, which removes most login spam.
Configurable time window
The filter period defaults to one second and can be increased in the config file to cover slower messages.
Vanilla messages kept
Standard game messages still appear during the window, so only the extra modpack text is removed.
Client-side operation
The filter runs on the player's client, so it changes nothing on the server and needs no server install.

Use cases
Large modpack logins
Players of big modpacks where a mod sends delayed welcome or status messages can log in without the chat filling up.
Pack testing
Pack developers can raise the window length to find how long their messages keep arriving after a world opens.
Who it’s for: Players who run large Forge modpacks with chat-heavy startup messages, and pack developers who want to tune the filter window for their own pack.

What the author says
This mod filters out any non-vanilla chat messages during a certain period after the world is opened. By default this period is 1 second, but this can be changed in the config. NOTE: Mod authors can (easily) deliberately work around what this mod does if they really want to and do their chat spam anyway, nothing you…
