my players hate being spammed about grinding. Can you make a config option to do silent blocking of grinding? Players don't need to be spammed about this.

I really miss this to, but I don't want it silenced, I would like a cooldown before the next message is sent.

"You are grinding, no more cash from you" --> Cooldown for 30 seconds starts, for every mob that is killed before the cooldown runs out, then the timer resets back to 30 seconds. So they will only get a new message if 30 seconds pass without killing a mob.

The spam is highly annoying when playing OneBlock or you're at an XP farm or similar.

Have you tried to clear the text in your lang file? (Dont delete the line - just clear the text)

Yes, i did do this after submitting this suggestion. I suppose that achieves the same result just not as known or user friendly? i was half expecting a stacktrace error or something dumb to happen when i did it.

Well - some server owners think there is enough settings in my config files and have complained about that, and given me a bad review on SpigotMc

It is hard to give everyone what they want :-)
