Mute in post game

Can you please make it so that if I mute someone in game, they're muted post game as well. If I have a bad game, and someone on my team is raging hard, the last thing I want to see is something along the lines of "WE ONLY LOST CAUSE OF XXX CHAMP REPORT UNINSTALL!!!!!!1!" it just adds to the frustration of doing bad and losing.
