YSK you can use a client mod to cut down on chat spam

↩  FromTimeToTime ↩  StevenNL2000 Me and some other admin use AdvancedChat, however there's some case stacked messages make things less readable, e.g. inspecting multiple blocks in a short time span.

I've been using the mod for quite some time and have actually created a configuration dedicated to administrating on the server.

It should be noted that Wurst has compatibility issues with AdvancedChat that prevent the chat from working properly.

Meteor also has a module that can reduce spam, its pretty effective and I use it all the time
