Information must go only to the people who really want them. Also this information must be useful and meaningful for the people in the communication process. Otherwise this information will not be useful for the people who receive them. This will waste the time of people. This movement of information does not add any value to the process of communication. This also takes additional resources of the system.
Unnecessary movement of information from one party to another can lead to alterations and distortions of the meaning of the messages. Misinterpretation of information also will be resulted from this. Needless to say that this is going to lead to problems.
