Request to Add mute to game

It has come to my attention that blacklisting people does not actually mute them in chat. This quiet the bummer, since nothing is more annoying than hanging out in FM and someone who refuses to purchases a store or a chalkboard decides that they are going to scream and shout to everyone about their products. In GMS this is one of the most useful tools to avoid conflict and block trolls and annoying people in general without resorting to complaining to mods about it. therefore I think it would be a really useful tool to be added to the game and request that it please be added to the game.
