Spam - The problem !
Unfortunately, they are also a fact of life on today's Internet. 600 million people have the ability to send us messages. Anonymity and instant, worldwide communications combined with our desire to be reachable make it impossible to prevent. Anyone can connect a computer to the Internet and send messages. Public computers abound. Unsafely operated computers are abundant and easily used by criminals. Laws are spotty and hard to enforce.
Spam (electronic)
Spamming is economically viable because advertisers have no operating costs beyond the management of their mailing lists, and it is difficult to hold senders accountable for their mass mailings. Because the barrier to entry is so low, spammers are numerous, and the volume of unsolicited mail has become very high. The costs, such as lost productivity and fraud, are borne by the public and by Internet service providers, which have been forced to add extra capacity to cope with the deluge. Spamming is widely reviled, and has been the subject of legislation in many jurisdictions.
