Internet censorship

(Redirected from Internet Censorship)

Internet censorship is the control or suppression of the publishing of, or access to information on the Internet. It may be carried out by governments or by private organizations at the behest of government, regulators, or on their own initiative. Individuals and organizations may engage in self-censorship for moral, religious, or business reasons, to conform to societal norms, due to intimidation, or out of fear of legal or other consequences[1].

What is it?

The blocking of content on the Internet from users in a country by a government or provider. This can be done because the content is prohibited by law or because the content is considered morally objectionable, or because the government or company does not like what is being said.

Executive Summary

The UK government has consulted on this issue and has concluded that people do not want the government to censor the Internet for them. However people do want the option of being able to download tools that help them control what they and their children will see on the Internet.

Most ISPs undertake limited censorship of web sites as a result of the threat of legal action from the police. They now block sites identified as containing child pornography and criminally racist content.

ISPs can be required to remove (or block access to) information of use to terrorist.

On the 15 May 2006 Vernon Coaker, Parliamentary Under-Secretary, Home Office set a deadline in a written answer of the end of 2007 for all ISPs to put in place technical measures that prevent their customers accessing websites containing illegal images of child abuse identified by the IWF.

The Times reports that the Britain's film censor is suggesting that it could provide the first classifications for content of the internet.

Exactly what is censored is unknown however in 2008 the cleanfeed list contained:

Blocks covering %
Entire sites 28
Individual pages with no extension at the end 18
Individual pages with .html or .htm extensions 10
Individual pages with image extensions 32
Individual pages other extensions 12

Problems and Concerns

False positives. The identification of material as problematic when it is actually harmless. For example, Vodafone's 3G services has been observed blocking technical blogs perhaps due to the sexuality of the author [1] even during outages to censorship system components.

Enforcement of a one-size-fits-all world view. Filters prepared by liberal organisations may block material from conservative organisations creating a unilaterally imposed barrier to free speech. Just because liberal ideas are popular (perhaps correctly so) does not mean that illiberal voices are always factually incorrect. There is a real danger of ignoring genuine problems or strong expressions of emotion because those voices cannot be heard. Similarly a liberal filter may allow content a conservative parent may not permit for their child. Finally a conservative filter may block material a liberal parent may be happy for a child to see.

These issues require that the implementation of censorship move away from ISPs and into the hands of parents. Simplistic laws mandating censorship at the ISP level may create real social harm.


On the 15 May 2006 Vernon Coaker, Parliamentary Under-Secretary, Home Office set a deadline in a written answer of the end of 2007 for all ISPs to put in place technical measures that prevent their customers accessing websites containing illegal images of child abuse identified by the IWF.

UK internet service providers (ISPs) continue to lead the world in tackling this issue and the majority are committed to taking all steps available to them to prevent users accessing illegal images of child abuse. This is evidenced, for example, by their commitment to and funding of the Internet Watch Foundation (IWF) and the reduction in the proportion of illegal sites reported to the IWF that are hosted in the UK from 18 per cent. in 1997 to 0.4 per cent. in 2005.
Recently, it has become technically feasible for ISPs to block home users' access to websites irrespective of where in the world they are hosted. It is clear from the various meetings that Ministers have had with the ISPs, that the industry has the will to implement solutions to block these websites. Currently, all the 3G mobile network operators block their mobile customers from accessing these sites and the biggest ISPs (who between them provide over 90 per cent. of domestic broadband connections) are either currently blocking or have plans to by the end of 2006.
We recognise the progress that has been made as a result of the industry's commitment and investment so far. However, 90 per cent. of connections is not enough and we are setting a target that by the end of 2007, all ISPs offering broadband internet connectivity to the UK general public put in place technical measures that prevent their customers accessing websites containing illegal images of child abuse identified by the IWF. For new ISPs or services, we would expect them to put in place measures within nine months of offering the service to the public. If it appears that we are not going to meet our target through co-operation, we will review the options for stopping UK residents accessing websites on the IWF list.

Section 3 of the Terrorism Act 2006 a measure that allows a constable to require ISPs to remove (or block access to) information of use to terrorist will instead need prior judicial approval.

In December 2000, a Communications White Paper stated that research suggests people want tools that help them control what they and their children will see on the Internet, "rather than third party regulation" and that government and industry partnership provides the best approach.

In this area, therefore, we will expect OFCOM to continue to support the Internet Watch Foundation's work to allow Internet users to regulate their own Internet experience, or that of their children, by using rating and filtering systems
it is important ... that users are aware of the tools available, such as rating and filtering systems, that help them control what they and their children will see on the Internet. Research suggests that this is what people want in relation to the Internet, rather than third party regulation.

A UK NGO named the Internet Watch Foundation has been established by Internet Service Provider associations to implement proposals to deal with illegal material on the Internet, with particular reference to child pornography and criminally racist content. The IWF's establishment followed the London Metropolitan Police sending a letter to all Internet Service Providers on 9 August 1996 requesting them to censor Usenet news groups or else police would find it necessary to prosecute ISPs in relation to illegal material made available via their systems.

ORG Censorship Monitoring Project

The ORG Censorship Monitoring Project aims to deploy a number of probes connected to various fixed-line and mobile ISPs to be able to test which sites are blocked by the various ISPs. The project aims to build on the reporting site and is in its initial stages.

Campaign against censorship on the Internet

Amnesty International together with The Observer and Soda Creative launched a campaign called irrepressible.Info against the increasing governmental censorship of the internet. The campaign asks governments to stop censoring websites, blocking emails or shutting down blogs and make an appeal to the big corporations to stop supporting these actions.

Outside the UK

There has been criticism of Internet companies doing business in China for compliance with censorship and breaches of user privacy. The US Congressman Tom Lantos (D-San Mateo/San Francisco) told the companies that they had accumulated great wealth and power, "but apparently very little social responsibility"

Your abhorrent actions in China are a disgrace. I simply don't understand how your corporate leadership sleeps at night.


Parry Aftab, an Internet privacy and security lawyer and executive director of, argues that educating children about potential dangers online is the way to keep them safe. "No one in any country, no matter how well meaning they are, can block everything," she says. "It's about education. And most of it has to be done at a home, school, or kid level. It's the only way to protect them."



The best place for information on this is Internet Censorship: Law & policy around the world, Electronic Frontiers Australia have done a very good job of covering this issue.


2008-01-17 - The Guardian - Caught in the web
Author: Frank Fisher
Summary: When asked to name countries that impose extensive internet censorship, you might think of China, Iran, or North Korea; I doubt you'd think of the UK, but, after the home secretary Jacqui Smith's speech to the International Centre for Study of Radicalisation and Political Violence today, you really should. Smith's headline-grabbing proposal, to use the same tools against "extremist" websites as are currently used against child pornography, should worry us all. Few hard details are available, but if we take her at her word this is a dangerous extension of government powers, with a dangerous lack of oversight.
2007-10-02 - The Guardian - Online censorship hurts us all
Author: Cory Doctorow
Summary: Since 1995, every single legislative initiative on this subject in the UK's parliament, the European parliament and the US Congress has focused on making it easier to suppress "illegitimate" material online. From libel to copyright infringement, from child porn to anti-terror laws, our legislators have approached the internet with a single-minded focus on seeing to it that bad material is expeditiously removed. And that's the rub. I'm certainly no fan of child porn or hate speech, but every time a law is passed that reduces the burden of proof on those who would remove material from the internet, artists' fortunes everywhere are endangered. Take the US's 1998 Digital Millennium Copyright Act, which has equivalents in every European state that has implemented the 2001 European Union Copyright Directive. The DMCA allows anyone to have any document on the internet removed, simply by contacting its publisher and asserting that the work infringes his copyright.

2007-01-27 - The Guardian - China censorship damaged us, Google founders admit
Author: Jane Martinson
Summary: Google's decision to censor its search engine in China was bad for the company, its founders admitted yesterday. ... Asked whether he regretted the decision, Mr Brin admitted yesterday: "On a business level, that decision to censor... was a net negative." ... Since moving into China, Google has been compared to Microsoft because of its dominant position and power. "We are very sensitive to people talking about us in that way," said Mr Brin. Mr Page described the differences between the two technology companies by saying "we have very open partnerships, we are very clear about being fair with revenues."

Author: Hannah Clark
Summary: Brin and Page also responded to the criticism that erupted when Google agreed to work with the Chinese government last year to limit search results in that country. Up until that point, Google had been fairly immune from the criticism that plagues most big companies. Brin said the damage to Google's image made the deal a "net negative." But Page wouldn't say it was a bad move. "I would hate for us as a company to make what we think is the wrong decision for people in China based on our reputation." ... Brin said he was instinctively opposed to the deal because he was born in the Soviet Union. "Having felt that kind of oppression, I would never have wanted to compromise in that direction." His opinion changed, he said, when he talked with Chinese people about it. "They’re really proud of what China has accomplished. They feel that as much information as can go into China, the better off it is."
