Which act restricts the use of facsimile machines to send unsolicited advertisements?

The Telephone Consumer Protection Act (TCPA) is the legislation that restricts the use of facsimile machines to send unsolicited advertisements. Enacted in 1991, the TCPA aims to reduce the number of unwanted and intrusive telemarketing calls and faxes that consumers receive. Specifically, it prohibits sending unsolicited advertisements via fax unless the recipient has given prior express permission to receive such communications or there is an established business relationship that permits it.

This act addresses the privacy concerns of individuals receiving unsolicited advertisements, which can clutter their fax lines and lead to unwanted interruptions. In contrast, other acts mentioned, such as the CAN-SPAM Act, primarily focus on regulating commercial email messages rather than fax communications. The Consumer Privacy Act deals generally with data privacy rather than the specifics of unsolicited advertisements. The Telemarketing Sales Rule governs telemarketing practices but does not specifically target fax advertising. Thus, the TCPA is the correct answer as it directly pertains to the regulation of unsolicited faxes.
