Summary

It makes it illegal, when the conduct affects interstate or foreign commerce, to knowingly send or help send large amounts of commercial email by dishonest means. That includes accessing a computer without permission and sending many commercial messages from it; using a computer to forward or relay commercial messages to hide where they came from; sending many commercial messages with fake header information; signing up for five or more email/online accounts or two or more domain names with false identity and using them to send many commercial messages; or pretending to control five or more IP addresses and sending many commercial messages from them. Conviction can bring a fine and up to 5 years in prison if the act furthered a felony or the person has a prior conviction for similar conduct. In other listed situations the punishment can be a fine and up to 3 years, including certain registration counts (20 or more falsified email/online accounts or 10 or more falsified domain names), large message volumes (exceeded 2,500 in 24 hours, 25,000 in 30 days, or 250,000 in 1 year), losses or gains of $5,000 or more in a year, or organizing a group of three or more. Other cases carry a fine or up to 1 year. A court must order forfeiture of proceeds and any equipment or software used to commit the offense, using the forfeiture procedures in 21 U.S.C. 853 (except subsection (d)) and Rule 32.2. Definitions: "loss" means the meaning in section 1030(e); "materially falsified" means altered or concealed so identification, location, response, or investigation is impaired; "multiple" means more than 100 in 24 hours, more than 1,000 in 30 days, or more than 10,000 in 1 year; other terms use the meaning in section 3 of the CAN-SPAM Act of 2003.
