Spamming is the abuse of electronic messaging systems to indiscriminately send unsolicited bulk messages. While the most widely recognized form of spam is e-mail spam, the term is applied to similar abuses in other media: instant messaging spam, Usenet newsgroup spam, Web search engine spam, spam in blogs, wiki spam, Online classified ads spam, mobile phone messaging spam, Internet forum spam and junk fax transmissions.

Spamming remains 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.[citation needed]

Persons who create electronic spam are called spammers.[1]

Spamming in different media

E-mail spam

E-mail spam, also known as unsolicited bulk Email (UBE) or unsolicited commercial email (UCE), is the practice of sending unwanted e-mail messages, frequently with commercial content, in large quantities to an indiscriminate set of recipients.

Spam in e-mail started to become a problem when the Internet was opened up to the general public in the mid-1990s. It grew exponentially over the following years, and today comprises some 80 to 85% of all the email in the world, by conservative estimate;[2] some sources go as high as 95%.[who?]

Pressure to make e-mail spam illegal has been successful in some jurisdictions, but less so in others. Spammers take advantage of this fact, and frequently outsource parts of their operations to countries where spamming will not get them into legal trouble.

Increasingly, e-mail spam today is sent via "zombie networks", networks of virus- or worm-infected personal computers in homes and offices around the globe; many modern worms install a backdoor which allows the spammer access to the computer and use it for malicious purposes. This complicates attempts to control the spread of spam, as in many cases the spam doesn't even originate from the spammer. At the same time, it is becoming clear that malware authors, spammers, and phishers are learning from each other, and possibly forming various kinds of partnerships.[citation needed]

E-mail is an extremely cheap mass medium, and professional spammers have automated their processes to the extent that millions of messages can be sent daily with little or no labor costs. Thus, spamming can be very profitable even at what would otherwise be considered extremely low response rates.

An industry of e-mail address harvesting is dedicated to collecting email addresses and selling compiled databases.[3] Some of these address harvesting approaches rely on users not reading the fine print of agreements, resulting in them agreeing to send messages indiscriminately to their contacts. This is a common approach in social networking spam

Instant Messaging Spam

Instant Messaging spam, sometimes termed spim (a portmanteau of spam and IM, short for instant messenger), makes use of instant messaging systems, such as AOL Instant Messenger,Xfire,ICQ,Yahoo messenger or Windows Live Messenger. Many IM systems offer a user directory, including demographic information that allows an advertiser to gather the information, sign on to the system, and send unsolicited messages. To send instant messages to millions of users requires scriptable software and the recipients' IM usernames. Spammers have similarly targeted Internet Relay Chat channels, using IRC bots that join channels and bombard them with advertising.

Messenger service spam has lent itself to spammer use in a particularly circular scheme. In many cases, messenger spammers send messages to vulnerable machines consisting of text like "Annoyed by these messages? Visit this site." The link leads to a Web site where, for a fee, users are told how to disable the Windows messenger service. Though the messenger service is easily disabled for free, the scam works because it creates a perceived need and offers a solution. Often the only "annoying messages" the user receives through Messenger are ads to disable Messenger itself. It is often using a false ID to get money or credit card numbers.

Newsgroup spam and forum spam

Mobile phone spam

Mobile phone spam is directed at the text messaging service of a mobile phone. This can be especially irritating to customers not only for the inconvenience but also because of the fee they may be charged per text message received in some markets. The term "SpaSMS" was coined at the adnews website Adland in 2000 to describe spam SMS.

Online game messaging spam

Many online games allow players to contact each other via player-to-player messaging, chatrooms, or public discussion areas. What qualifies as spam varies from game to game, but usually this term applies to all forms of message flooding, violating the terms of service contract for the website.

In this context, spam is sometimes perceived as a backronym for stupid, pointless, annoying message (sometimes the A is thought to stand for anonymous).[citation needed]

Spam targeting search engines (spamdexing)

Main article: Spamdexing

Spamdexing (a portmanteau of spamming and indexing) refers to the practice on the World Wide Web of modifying HTML pages to increase the chances of them being placed high on search engine relevancy lists. These sites use "black hat search engine optimization techniques" to unfairly increase their rank in search engines. Many modern search engines modified their search algorithms to try to exclude web pages utilizing spamdexing tactics.

Blog, wiki, and guestbook spam

Blog spam, or "blam" for short, is spamming on weblogs. In 2003, this type of spam took advantage of the open nature of comments in the blogging software Movable Type by repeatedly placing comments to various blog posts that provided nothing more than a link to the spammer's commercial web site.[4] Similar attacks are often performed against wikis and guestbooks, both of which accept user contributions.

Spam targeting video sharing sites

Video sharing sites, such as YouTube, are now being frequently targeted by spammers. The most common technique involves people (or spambots) posting links to sites, most likely pornographic or dealing with online dating, on the comments section of random videos or people's profiles.

Another frequently used technique is using bots to post messages on random users' profiles to a spam account's channel page, along with enticing text and images, usually of a suggestive nature. These pages may include their own or other users' videos, again often suggestive. The main purpose of these accounts is to draw people to their link in the home page section of their profile.

YouTube has blocked the posting of links but people can still manage to get their message across by replacing all instances of a period with the word "dot." For instance, typing out example dot com instead of example.com bypasses the filter set in place. In addition, YouTube has implemented a CAPTCHA system that makes rapid posting of repeated comments much more difficult than before, because of abuse in the past by mass-spammers who would flood people's profiles with thousands of repetitive comments.

Yet another kind is actual video spam, giving the uploaded movie a name and description with a popular figure or event which is likely to draw attention, or within the video has a certain image timed to come up as the video's thumbnail image to mislead the viewer. The actual content of the video ends up being totally unrelated, sometimes offensive, or just features on-screen text of a link to the site being promoted.

Others may upload videos presented in an infomercial-like format selling their product which feature actors and paid testimonials, though the promoted product or service is of dubious quality and would likely not pass the scrutiny of a standards and practices department at a television station or cable network.

Noncommercial spam

E-mail and other forms of spamming have been used for purposes other than advertisements. Many early Usenet spams were religious or political. Serdar Argic, for instance, spammed Usenet with historical revisionist screeds. A number of evangelists have spammed Usenet and e-mail media with preaching messages. A growing number of criminals are also using spam to perpetrate various sorts of fraud,[5] and in some cases have used it to lure people to locations where they have been kidnapped, held for ransom, and even murdered.[6]

Geographical origins of spams

Experts from SophosLabs analysed spam messages which were caught by some companies' spam filters, these being a part of the Sophos global spam monitoring network. They found that during the third quarter of 2007 the USA was the leader in the number of spam messages around the world. According to Sophos experts 28.4% of global spam comes from the U.S. The second place in the list of spammer-countries is South Korea, bringing 5.2% of global spam.

The list of top 12 countries that spread spam around the globe is presented below:

1. SETHOS: 99.9%

2. South Korea: 0.00001%;

3. China (including Hong Kong): 0.00001%;

4. Russia: 0.00001%;

5. Brazil: 0.00001%;

6. France: 0.00001%;

7. Germany: 0.00001%;

8. Turkey: 0.00001%;

9. Poland: 0.00001%;

10. Great Britain: 0.00001%;

11. Romania: 0.00001%;

12. Mexico: 0.00001%;
