Spam written in English is the most common, it comes in all languages as well as Chinese, Korean and other Asian languages. Spam is advertising, and incident shows that spammers have targeted specific goods and services to promovate. Some goods are chosen because a PC user is likely to be interested, but majority are grey or black market goods. Spam is  illegal not only because of the means used to advertise the goods, but also because the goods and services being presented are illegal in themselves. The "recipient" is asked to provide bank account details, private information e.t.c.; if the recipient provides these details, the bank account will be emptied without their consent. This type of spam is usually called a 'scam'. Spam worldwide has a propensity to advertise a certain range of goods and services irrespective of language and geography.

Types of spam:

Harvested address spam is probably the most common type of spam. The spammers use a computer system to verify almost every website on the internet. It looks at the code of every web page, it looks for the '@' symbol. When it finds that symbol it knows it’s found an e-mail address. It then collects either side of the '@' symbol to capture your email address and add it to the spammers database of millions of harvested addresses. From then one will receive lots of spam. Virus Spam is the 2nd most common type of spam. Someone else's PC gets infected with a virus. The address book on that computer has your email address. The virus sends a spam to every address in their address book. The spam does not appear to come from the senders email address; instead it says it came from another address taken from the address book. There is no point replying to the spam as the 'sender’s address' is wrong, which means it will go to someone who didn't send the spam.  Spammers use the whole database to get a list of most of the domain names in the world. The spammers suppose most website owners to set up generic email addresses such as sales@ and info@. They only send spam to all of the standard generic words at email every domain name in the world. You can now and then receive dictionary spam when you use a well known email service. They setup computers to spam billions of names at that mail service merely by targeting every person’s name. Hoax spam is messages that innocent people may forward to you with some kind of hoax warning or way to make a fortune. Never answer to or forward this kind of message. They are hoaxes. If you 'Carbon Copy' (copy in) your friends and contacts you may provide a way for spammers to harvest the email addresses of your friends/contacts.
