Spam
It is e-mail that is unsolicited, unwanted, irrelevant, or inappropriate, especially commercial advertising in mass quantities. Spam is often sexually suggestive or offensive in other ways.
Examples:
While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, spam in blogs, online classified ads spam, mobile phone messaging spam, social networking spam.
Stay Safe:
The best way to prevent spam is to protect your e-mail address. Don't respond to free offers or web sites that ask you for your e-mail. If you are already getting spam, then change your e-mail address. Your Internet service provider can also help prevent your receiving spam. You can generally fix your e-mail preferences to filter out much of the spam.
