Does short message call names constitute libel?

It's not a crime of libel to keep insulting by SMS. To constitute the crime of libel, there must be acts of fabricating facts to slander others, such as fabricating facts that damage others' reputation and spreading them on the information network, or organizing and instructing people to spread them on the information network. Moreover, short message abuse does not belong to the act of fabricating facts to slander others, so it does not constitute libel.

legal ground

Article 1 of the Interpretation of the Supreme People's Court and the Supreme People's Procuratorate on Several Issues Concerning the Application of Laws in Handling Criminal Cases such as Defamation through Information Network shall be deemed as "fabricating facts to slander others" as stipulated in the first paragraph of Article 246 of the Criminal Law: (1) fabricating facts that damage the reputation of others and spreading them on the information network, or organizing or instructing personnel to spread them on the information network; (2) Tampering with the original information content involving others on the information network as a fact that damages the reputation of others, spreading it on the information network, or organizing or instructing personnel to spread it on the information network. Knowing that it is a fabricated fact that damages the reputation of others and spreads it on the information network, if the circumstances are bad, it is regarded as "fabricating facts to slander others".
