Title 18 › Part I— CRIMES › Chapter 47— FRAUD AND FALSE STATEMENTS › § 1037
It is illegal to use computers and the Internet to send lots of commercial emails while hiding or lying about where they come from. That includes accessing a protected computer without permission to send many commercial messages; using a computer to relay messages to trick recipients or Internet providers about origin; changing header information to hide the sender; signing up for five or more email or user accounts (or two or more domain names) using false identity and sending many commercial messages from them; or pretending to control five or more IP addresses and sending many commercial messages from those addresses. Punishments vary by seriousness. If the crime furthers another felony or the person has a past similar conviction, the penalty is a fine, up to 5 years in prison, or both. Certain other aggravating facts (including specific registration or volume counts, $5,000 or more in losses or gains in a year, or leading a group of three or more) bring fines or up to 3 years. Other cases bring fines or up to 1 year. Courts must order the offender to forfeit profits and any gear, software, or technology used to commit the crime. The law uses the definition of “loss” from 1030(e). “Materially falsified” header or registration means altered so people or investigators can’t identify or find the sender. “Multiple” means >100 in 24 hours, >1,000 in 30 days, or >10,000 in a year. Other terms use the CAN-SPAM Act definitions.
