What Is Spam?

'Spam' is the blanket name given to a variety of different practices, the common feature of which is that they all involve the use of electronic messaging systems to indiscriminately send out bulk messages. Perhaps the most widely recognised form of spam is email spam, but there are a number of variants including blog and forum comment spam, instant messaging spam and social networking spam. Some estimates have placed the number of spam messages sent during 2011 at somewhere around 7 trillion messages.CPA google bing
