Right now, chat muting (/mute) in realm chat is close to useless since players can change their names or log into new accounts to get around it. This leads to realm chats becoming dominated by one or a few users that frequently create new accounts to post inflammatory comments.
Instead, players should be able to automatically mute chatters who have been muted by too many of their kin. This will offload work of muting, making it so that one player's action only requires a few players' response rather than the response of everyone reading realm chat. It could also have a side benefit of encouraging new players to make friends with nearby neighbors who can do the muting for them.
