A more thorough explanation:

The CAN-SPAM Act of 2003 is a law that regulates commercial email messages sent to consumers. Section 6 of the Act states that businesses can be held responsible if they knowingly benefit from emails sent by spammers that contain false or misleading information in the email header. This means that if a business hires a spammer to send emails on their behalf, they can be held liable for any violations of the Act.

For example, if a company hires a spammer to send emails advertising their products, and the spammer uses false information in the email header, such as a fake sender name or email address, the company can be held responsible for the spammer's actions.

Section 3 of the CAN-SPAM Act also holds companies responsible if they use spammers to advertise for them. This means that if a company hires a spammer to send emails on their behalf, they are also responsible for ensuring that the emails comply with the Act.

For example, if a company hires a spammer to send emails advertising their products, and the spammer includes false or misleading information in the email, such as false claims about the product or deceptive subject lines, the company can be held responsible for the spammer's actions.

In summary, the CAN-SPAM Act of 2003 holds businesses responsible for any violations of the Act committed by spammers they hire or benefit from. This is to ensure that companies take responsibility for the emails they send and that consumers are protected from deceptive or fraudulent emails.
