但诽谤法律在韩国是有问题的,因为网络诽谤的惩罚不提供任何防御诽谤通过互联网通信类似出版物的刑法承认真实的诽谤公共利益.Defamation法律可能无法攻击一个适当的平衡言论自由和声誉的原因。人们只是想表达他们的感受，并带来公共利益。然而，诽谤法完全是正当的，这是有问题的。与其他一些国家的法律类似，韩国法律禁止无端诽谤。如果一些人只是想在Facebook上表达他们的感受，这很难证明是合理的。辩护或证明事实已被认为是对诽谤指控的绝对抗辩。真理的证明总是或几乎总是一种完全的辩护。对事实的辩护是有条件的，综上所述，说明了诽谤法的寒蝉效应。诽谤法对言论自由的寒蝉效应是，人们不太可能说出自己的想法。它也使人们表现出克制和谨慎。我认为诽谤是不道德的，但我不认为它是非法的。诽谤是为了保护名誉不受不公正的攻击。诽谤是保护人们站起来面对世界的能力的根本。阻碍言论自由和保护有权势的人不受调查是令人反对的(Dent, C. & Kenyon, 2004)。用真理诽谤人是可能的。真理仍然会不公平地伤害人。但是，我们不能区分什么是表象，什么是行动，因为行动和世界其他地方是有区别的。人们可以通过引起别人对一个人的负面意见或引起恐慌来攻击某人。人们可以用语言做很多伤害。伤害原则是对他人行为的一种限制。
But defamation law is problematic in Korea because the punishment of internet libel does not provide any defenses for libel through internet communication similar to what the criminal code recognizes in publication of truthful defamation for the public interest .Defamation laws may fail to attack an appropriate balance between freedom of expression and reputation for a number of reasons. People just want to express their feelings, and bring in a public interest. However it is problematic that defamation laws are justified at all. Similar with the laws in some other countries, Korean law prohibits unjustifiable defamation. If some people just want to express their feelings on Facebook, it is hard to justify. Justification or proof of truth has been recognized as an absolute defense against a claim of defamation. Proof of truth is either always or almost always a full defense. The defense of truth is qualified .In conclusion, the above illustrated the chilling effect of defamation law. The chilling effect of defamation law on freedom of expression is that people are less likely to say what they think. It also makes people show restrained and caution. I think that defamation is something that is immoral, but I do not think it should be illegal. Defamation is supposed to protect reputation from unfair attack. Defamation is a fundamental of protection of people’s ability to stand up and face the world. It is objectionable is to obstruct free speech and protect powerful people from investigation (Dent, C. & Kenyon, 2004). It is possible to defame someone with truth. Truth can still harm unjustly. However, we cannot make the distinction between what is representation and action, because there is a distinction between the act and the rest of the world. People can assault somebody by causing others to form an adverse opinion of a person or cause panic with words. People can do a lot of harm with words. The harm principle is a restriction on other people’s actions.
