What about text messages that have been harassed all the time? Can I call the police?

Legal analysis: you can call the police or report. Citizens' freedom and safety of communication are protected by law. Telephone harassment itself is an infringement, and the parties concerned should bear civil liability. If it involves extortion, it should also bear legal responsibility. Although a victim's money does not reach the legal standard, it will constitute a crime if the sum of the money of multiple victims exceeds the legal standard. Beyond this standard, he can still be investigated for his criminal behavior.

Legal basis: Article 287 of the Criminal Law of People's Republic of China (PRC) uses information networks to set up websites and communication groups that commit fraud, teach criminal methods, make or sell prohibited items and controlled items, which will constitute the crime of illegal use of information networks.
