Hello,
Would it be possible to avoid any untimely disturbances on the chat rooms, and this in the interest of all the players who use the "chat 'rooms" to communicate in a friendly manner.
YES, there is the application (mute button) which mutes the person who bothers you in the way of expressing yourself and of transcribing in clear the writings of a pseudo sanctioning a demerit (black ball) in the only one goal that all players can read the writings, criticisms or insults of the person sanctioned.
This application automatically removes the writings of the nickname from your chat strip ', however it continues to be read by other players who will also have to use the application and so on.
If they don't, you will continue to read the answers given and you will be forced to transfer those and so on. Which becomes unmanageable in the long run.

 Would it not be more judicious to proceed to the impossibility of communicating for the person who is sanctioned and this even removed, this for the duration of the sanction.

Or more simply add a rule of "behavior" in the rules of use under the following caption.
3.19 It is not advisable to dismiss a pseudo demerit in order to transcribe or respond in clear about his writings. Please make your dialogues in private message.
