It is the basis of legislation and original idea is to protect privacy, to prevent commercial fraud, stop network rumors, etc. But the results may not be as good as the default.
To prevent rumors system as an example. The official default is: if the information system, publishers can't all; But information promulgator default is the opposite: because the system, he may not speak the truth. The official default is: is the system of "the rumor mongers" deterrent; And information promulgator default is: the system is to tell the truth is deterrent.
I think, a healthy society to have a tolerance rumors of space. The following reasons:
A, in the information fast cross flow, rumors will soon be revealed, the rumor mongers credit will go bankrupt, the rumor mongers always in a relatively marginal role.
A, if you ask everyone speak the truth, may be who also dare not to speak, because he opens his mouth might say the wrong thing, may be "rumor".
A person that information is often not comprehensive, strictly speaking is "rumor", but if everyone put their mastery of the "rumor" out, away from the truth may is not far away.
You may say, not a lot of rumors to social harm? B: yes. The rumor is information along, you want to put an end to it, unless you comprehensive forbidden to speak. However, the rumor is in the information to the free flow of social harm, or is it big in the information control social harm? The free flow of information society, the rumor will be automatically clear.
