Stop  Spam
When I first got an e-mail account ten years ago, I
received communications only from family, friends, and
colleagues. Now it seems that every time I check my e-mail, I
have an endless series of advertisements and other
correspondence that do not interest me at all. If we want e-mail
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 e-mails almost
instantly. As more and more advertisers turn to spam to sell
their products,  individual(个人的) e-mail boxes are often
flooded with spam e-mails. Would people continue to use e-mail
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 e-mails contain computer viruses that can
shut down the entire network of a company. Companies rely on
e-mail 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, passes 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. E-mail
is a tool which helps people all over the world to communicate
conveniently, but spam is destroying this convenience.
