The messages almost inevitably go to those who did not request it. Most SPAM mail contains sexually explicit material, and other possibly illegal material. Please refrain from using E-Mail for advertising. Transmission of any material in violation of any local law or regulation is prohibited. This includes, but is not limited to, copyrighted material, material legally judged to be threatening or obscene, or material protected by trade secret.
Commercial advertising is an accepted use of the Internet.
However, there are appropriate and inappropriate places for Internet advertising. Unsolicited commercial advertisements are not allowed in email, and will result in account suspension or cancellation. This includes, but is not limited to, bulk-mailing of commercial advertising, informational announcements, and political tracts. Such material may only be sent to those who have explicitly requested it. Commercial advertisements are unwelcome in most Usenet discussion groups and on most email mailing lists.
