muting players ingame and emotes...

Why does muting a person ingame still forces me to hear their emote spam!? I was just in an aram with a heimer who literally spammed stupid emotes ALL GAME LONG! After muting him didn't help I asked him to stop but of course it made him follow me and spam i even more..... It literally started giving me a headache and made me mute the my sound completely..

So yeah... please make it so if I mute a player ingame I don't hear ANYHTHING from that player.

Thanks.
