随着垃圾邮件的泛滥，利用法律来保护网络用户的呼声越来越高了。
Stop Spam!
When I first got an email account ten years ago，I received communications only from family，friends，and colleagues.Now it seems that every time I check my email，I have an endless series of advertisements and other correspondence that do not interest me at all.If we want email to continue to be useful，we need specific laws that make spamming(发送垃圾邮件)a crime.
If lawmakers do not do something soon to prohibit spam，the problem will certainly get much worse.Computer programs allow spammers to send hundreds of millions of emails almost instantly.As more and more advertisers turn to spam to sell their products，individual(个人的)email boxes are often flooded with spam emails.Would people continue to use email if they had to deal with an annoying amount of spam each time?
This problem is troubling for individuals and companies as well.Many spam emails contain computer viruses that can shut down the entire network of a company.Companies rely on email for their employees to communicate with each other.Spam frequently causes failures in their local communications networks，and their employees are thus unable to communicate effectively.Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks.These computer problems raise production costs of companies，which are，in the end，passed on to the consumer.
For these reasons，I believe that lawmakers need to legislate(立法) against spam.Spammers should be fined，and perhaps sent to prison if they continue to disturb people.Email is a tool which helps people all over the world to communicate conveniently，but spam is destroying this convenience.
