The Difference Between Defamation and Insults

Aggressive and negative comments posted on bulletin boards are often referred to as “defamation” or “insults.” Let’s clarify the definitions and differences between these terms.
Whether the Content is Based on Fact
Defamation is a term that combines “slander” and “libel.” In terms of meaning, “slander” refers to the act of speaking ill of someone, while “libel” means to hurt someone by stating unfounded content. Therefore, the term “defamation” does not only mean speaking ill of someone but also harming someone with content that lacks any evidence.
Possibility of Criminal Punishment Even if Based on Fact
Just because something stated or posted is based on fact, it does not mean it is acceptable. Depending on the content of the post, one may be subject to criminal penalties under the Penal Code’s Defamation (Article 230) or Insult (Article 231).
The crime of defamation is established when someone publicly discloses facts and damages a person’s reputation. Posting specific facts on a bulletin board site that can be viewed by an unspecified number of people, thereby damaging someone’s reputation or threatening their social status, carries the risk of being subject to defamation law.
Even if the content is true, it can still constitute defamation; therefore, whether it is a lie or a statement based on facts, the risk of facing criminal penalties remain the same.
Furthermore, the crime of insult is established when a person is publicly insulted, even without stating facts. It is established when a person is publicly insulted, even without stating specific facts. It is established when a person is publicly insulted using language that disparages or demeans them, rather than citing specific facts. If you post disparaging statements about someone on bulletin boards, there is a risk of being charged with the crime of insult and facing criminal penalties.

If a company ignores bulletin boards, it can lead to a decline in the company’s reputation among viewers. Furthermore, if the content spreads beyond the bulletin boards, the damage can be even worse.
Decrease in Employee Motivation
The consequence of defamation extends beyond corporate reputation to the motivation of employees. The feeling of ‘working in a place viewed negatively by the public’ can decrease motivation and productivity. Furthermore, if employees begin to resign, this could result in a loss of talent.
If negative comments are left unaddressed and remain visible to an unspecified number of people on bulletin boards, the company’s reputation may deteriorate progressively, potentially making it difficult to recruit new talent. Furthermore, combined with a decline in employee motivation, this creates the risk of making it harder to retain employees.
