Secure your Inbox

There are some descriptions to describe what spam is, here I quote two definitions of spam to give reader a clear look.

From Wikipedia:

Spam is the abuse of electronic messaging systems (including most broadcast media, digital delivery systems) to send unsolicited bulk messages indiscriminately. 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, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, online classified ads spam, mobile phone messaging spam, Internet forum spam, junk fax transmissions, social networking spam, television advertising and file sharing network spam.

From Abuse.net:

Spam is flooding the Internet with many copies of the same message, in an attempt to force the message on people who would not otherwise choose to receive it. Most spam is commercial advertising, often for dubious products, get-rich-quick schemes, or quasi-legal services. Spam costs the sender very little to send — most of the costs are paid for by the recipient or the carriers rather than by the sender.

In short words, spam is anything that you don’t expect/ask to come.

If you don’t expect any advertising mails from some company, it’s a spam. If you receive a text message from your cellular operator and you never expect or ask it, you can call it spam.

On the next article, I will write why spam is bad.
