Is it illegal to send text messages to threaten others?

Legal analysis: threatening others may constitute the crime of provoking trouble. In addition, if it is not a simple act of intimidation, there are other situations as follows: asking for property during intimidation may constitute the crime of extortion, publishing false explosive, toxic, radioactive, infectious disease pathogens and other substances, or fabricating terrorist information such as explosion threat, biochemical threat and radiation threat, or deliberately spreading it knowing that it is fabricated terrorist information, which may seriously disrupt social order and constitute the crime of publishing false dangerous substances.

Legal basis: Article 274 of the Criminal Law of People's Republic of China (PRC) is the crime of extortion of public or private property. Whoever extorts or extorts public or private property for a large amount or many times shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or public surveillance, and shall also, or shall only, be fined for a huge amount or if there are other serious circumstances, shall be sentenced to fixed-term imprisonment of not less than three years but not more than 10 years, and shall also be fined.
