Junk

 

a wooden cargo sailboat with two to four masts, used for navigating the rivers and seacoasts of Southeast Asia. During the era of sailing ships, junks were used for military purposes; today they are used for transporting cargo, frequently also serving as dwellings. Junks have a shallow draft and a cargo capacity of up to 600 tons. Other characteristics include a very broad, almost rectangular, upraised prow and stern and quadrangular sails made of mats and bamboo poles.

What does it mean when you dream about junk?

Junk symbolizes things that need to be let go of and discarded. In a dream, junk can also indicate rejected parts of the self that need to be reappropriated.

spam

(1) See Web spam and spam phone call.

(2) Email that is not requested. Also called "junk email," "gray mail," "unsolicited commercial email" (UCE) and "unsolicited bulk email" (UBE), the term is both a noun (the email message) and a verb (to send it). Spam is used to advertise products or to broadcast political or social commentary.

The term was supposedly coined from a Monty Python comedy sketch in the early 1970s, in which every meal in a restaurant contained SPAM, Hormel's processed meat (in England in World War II, SPAM was always available while other foods were rationed). Spam may also mean "sales promotional advertising mail" or "simultaneously posted advertising message."

A Social Plague
Like viruses, spam has become a scourge on the Internet as billions of unwanted messages are transmitted daily. Unfortunately, as an advertising medium, spam produces results (see "Why Do They Do It" below). In order to reduce spam for their customers, ISPs have added an enormous number of servers that do only filtering (see spam filter). Unsolicited phone calls are another form of spam and perhaps even more of a nuisance (see robocall).

On January 1, 2004, the CAN-SPAM act became law in the U.S., which provides severe penalties for spammers, if they can be located (see CAN-SPAM). See image spam, SPIM, SPIT, mobile phone spam, form spam, mail bomb, Joe Job, SPF, letter bomb, spamdexing, Blacklist of Internet Advertisers, munging, RBL, ROKSO, MAPS, spam relay, spam trap, botnet, rogue site and opt-in.

Why Do They Do It?


Simple math. Suppose that out of 4,000 spam messages, one person buys something, and the spammer makes USD $1. If two million spams were sent that day, the spammer made $500, and the job took a half hour to set up. A few hours per week could yield $100,000 a year. Is that enough incentive for techie teenagers? Of course, consistent revenue is not guaranteed, but there is ample motivation.

Filters Create Even More Spam
As spam filtering becomes more sophisticated, spammers send even more spam to make the same profit, but email address lists can be hijacked or purchased for very little. There is a thriving business selling lists to spammers as well as lists of compromised computers (see zombie). There are even spam service providers that will do all the work (gotta love that entrepreneurial spirit!).

Easy to Rationalize
Spammers justify their existence by citing the huge amount of physical junk mail sent via the postal system, wasting trees and other resources. They also claim advertisers have been polluting the environment with radio, TV, bus and billboard ads for decades. Nevertheless, a standard for authenticating email could eliminate most spam. Unfortunately, that can take years to implement worldwide (see email authentication).
