THIS PLUGIN IS DISCONTINUED ON BUKKIT. CHECK OUT SPIGOT FOR UPDATES: https://www.spigotmc.org/resources/messagehider.91661

Warning: If you're updating from plugin version 1.8: The config got updated so you have to recreate it. When the plugin loads it will automatically rename the old config to config.yml.old and create a new one. It's advisable to recreate filters by using /mh create.

With this plugin you can hide or replace the messages you receive. For example you can filter [Server: The player idle timeout is now X minutes]. You can also execute commands when a filter applies.
There are 4 presets at the moment:

idle timeout (as mentioned),
gamemode change (You don't receive the message if another player changes their gamemode)
only self commands (You only receive feedback for your own commands) 1.16+
console commands (Operators do not receive messages from commands sent by the console)

You can even create own filters and have various settings to do this. For more information check out the Github page.

This plugin collects anonymous server stats with bStats, an open-source statistics service for Minecraft software. If you don't want this, you can deactivate it in plugins/bStats/config.yml.
