A more thorough explanation:

Definition: Wisconsin has laws in place to regulate telemarketing and telephonic anti-solicitation, fax anti-solicitation, and pornography. These laws include:

• Wisconsin Statutes §§ 100.52 and 100.525, which regulate telemarketing and telephonic anti-solicitation
• Wisconsin Statute § 134.73, which regulates fax anti-solicitation
• Wisconsin Statute § 944.25, which regulates pornography

For example, Wisconsin Statutes §§ 100.52 and 100.525 require telemarketers to identify themselves and their purpose for calling, and to honor requests to be placed on a do-not-call list. Wisconsin Statute § 134.73 prohibits unsolicited fax advertisements. Wisconsin Statute § 944.25 prohibits the distribution of certain types of pornography.

These laws are in place to protect consumers from unwanted solicitations and to regulate the distribution of potentially harmful materials.
