Final answer:
The e-mail spamming operation by Edward Davidson violated the CAN-SPAM Act, which governs the sending of commercial emails and specifies requirements to prevent deceptive practices.
Step-by-step explanation:
Edward Davidson ran a spamming operation out of his home that sent hundreds of thousands of spam e-mails, with the header information of these e-mails concealing the actual sender from the recipient of the e-mail. This is a violation of the Combating the Assault of Non-Solicited And Marketing (CAN-SPAM) Act which was enacted in 2003 by the U.S. Congress. The CAN-SPAM Act sets the rules for commercial email, establishes requirements for commercial messages, gives recipients the right to have emails stopped from being sent to them, and spells out tough penalties for violations.
The purpose of the CAN-SPAM Act is to set guidelines for the sending of commercial emails and to protect users from misleading and unwanted electronic communication. It addresses issues including but not limited to requiring accurate header information, clear subject lines, a valid physical address of the sender, and the inclusion of an opt-out mechanism for recipients. Violations can lead to significant fines and can constitute a federal criminal offense.
