Mailing Obscene Material is the act of sending obscene written or visual materials through the postal system, or other means of delivery, such as email or social media. This includes sending images or videos that depict sexual acts, as well as obscene literature or other materials. The two main types of Mailing Obscene Material are sending material through the postal system (including by email and social media) and sending material through a computer network. Sending material through the postal system may involve sending books, magazines, pictures, films, or other materials that are considered obscene. Sending material through a computer network may involve sharing images, videos, or text messages that are of an obscene nature. In the United States, Mailing Obscene Material is a federal offense and can result in fines or imprisonment. In some countries, sending obscene materials through the mail is a criminal offense. In other countries, sending obscene materials through the mail may be considered a civil offense.
