Shadow muted
In online chat rooms moderators police the content and if necessary, they can normally mute users who are breaking the rules. A shadow mute is when the player is muted but isn't informed of the mute. Often they continue to chat, completely unaware that nobody in the chatroom can see what they type. The shadow muted user is left with the feeling that nobody is interested in them or whatever it is they have to say. Its a particularly cruel form of muting and can cause long term self esteem issues in tweens.
