What is it

Spam is the use of messaging systems such as email to send unsolicited messages, especially advertising, as well as sending messages repeatedly on the same site. Spammers collect email addresses from chat rooms, websites, customer lists, newsgroups, and viruses that harvest users' address books. These collected email addresses are sometimes also sold to other spammers.
