India's Forgotten Faces www.motherjones.com/photoessays/2009/02/indias-forgotten-faces/18

The adivasi, or indigenous, people of southern India are among the poorest in the world. Ignored by the classical caste structure and shunned by the government, adivasi communities have relied for centuries on India's forests for food, fuel, and cultural identity. But with increasing pressures from large scale agriculture, and the growth of conservation zones and national parks, today their open access to the forest has almost(?) disappeared. Some particularly marginalized communities were forcefully relocated out of the forest into government-built houses.

internet pollution

Front groups is one astroturfing technique, which typically creates the appearance of being an organization that serves the public interest, while masking a corporate sponsor.
-content farm
Critics allege that content farms provide relatively low quality content, and that they maximize profit by producing "just good enough" material rather than high-quality articles. Articles are usually composed by human writers rather than automated processes, but they may not be written by a specialist in the subjects reported. Some authors working for sites identified as content farms have admitted knowing little about the fields on which they report. Search engines see content farms as a problem, as they tend to bring the user to less relevant and lower quality results of the search. The reduced quality and rapid creation of articles on such sites has drawn comparisons to the fast food industry and to pollution:

Information consumers end up with less relevant or valuable resources. Producers of relevant resources receive less cash as a reward (lower clickthrough rate) while producers of junk receive more cash. One way to describe this is pollution. Virtual junk pollutes the Web environment by adding noise. Everybody but the polluters pays a price for Web pollution: search engines work less well, users waste precious time and attention on junk sites, and honest publishers lose income. The polluter spoils the Web environment for everybody else.

The U.S. military is developing "Operation Earnest Voice" to use sockpuppetry software that will "fake online personas to influence net conversations and spread US propaganda
Online forum manipulation strategies can take many forms, and firms (or, depending on the context of interest, political parties and special interest groups) are getting more sophisticated about them by the day. The simplest firm strategy is to anonymously post online reviews praising its own products, or bad-mouthing those of its competitors. There is ample evidence that such manipulation takes place.

Data mining expert Bing Liu (University of Illinois) estimated that one-third of all consumer reviews on the Internet are fake. According to the New York Times, this has made it hard to tell the difference between "popular sentiment" and "manufactured public opinion." According to an article in the Journal of Business Ethics, astroturfing threatens the legitimacy of genuine grassroots movements. The authors argued that astroturfing that is "purposefully designed to fulfill corporate agendas, manipulate public opinion and harm scientific research represents a serious lapse in ethical conduct." A 2011 report found that often paid posters from competing companies are attacking each other in forums and overwhelming regular participants in the process. George Monbiot said persona management software that supports astroturfing, "could destroy the Internet as a forum for constructive debate."
