spam
to sell products has become a major problem as it makes computer communication more difficult.
Many companies that want to send a great deal of advertising at the same time might use the services of a "spammer". A spammer is a person or company that uses computers to send out millions of copies of the same sales information. Spammers get people’s e-mail addresses from websites, news groups and "chat rooms" where people send messages to each other.
Most spam is sent by companies that are trying to get you to buy their products. Some of these are honest companies that may offer good products or services for fair prices. These companies can offer their products for a cheaper price than you might find in a store. However, much of the spam on the Internet is sent by criminals (罪犯) who are trying to sell products that do not exist or offer services they will not provide at all. What they are only interested in is stealing your money. When you answer their spam you find you are expected to send them money and receive a gift. If you just follow what they ask you to do without any consideration, it is likely that you will be cheated and lose some money.
