hey! 
i think the ability to mute people would help players with people bothering / harassing them. this would help especially in ffa, where people talk smack to eachother.

You can /ignore (ign) it does basically the same thing, guessing you're not talking about literally muting them

If you would like to mute someone, you are able to use /ignore (ign) to mute direct messages from that player. However, if you feel like they are harassing you or another player, then please use /report.
