Internet Censorship: As Bad As You Thought It Was

Maybe a bit worse, actually

WHAT THEY DON’T SEE

China is one of the 25 countries found to systematically filter its citizens’ Internet content.

”In the dot-com heyday of the ’90s and early 2000s…there was a myth that the Internet can’t be controlled,” says Ronald Deibert, a researcher at the University of Toronto’s Citizen Lab. ”There was some mysterious, magical property associated with it that will route around censorship.” The most exhaustive study yet of Internet censorship—Access Denied: The Practice and Policy of Global Internet Filtering, published this month by the MIT Press—pretty much disproves that notion.

The report’s authors, the OpenNet Initiative—a multi­disciplinary team at the University of Toronto, and Cambridge, Harvard, and Oxford universities—sent investigators to 41 countries that had been rumored to filter Internet content, whether to silence political dissent or to block access to pornography or religiously and culturally divisive material.

ONI set out to objectively confirm or invalidate the reports. It found that the situation was worse than the rumor mill suggested. ”The big thing is that the scope, scale, and sophistication of Internet content filtering is on the rise worldwide, and it’s really an alarming increase,” says Deibert, one of the book’s editors and contributors.

ONI discovered systematic Internet filtering in 25 countries, with nine of them—China, Ethiopia, Iran, Myanmar, Saudi Arabia, the United Arab Emirates, Uzbekistan, Vietnam, and Yemen—blocking content in every category it investigated.

”The vast majority of ­content [around the world] that is blocked is ­pornography,” Deibert says. ”But what we’re seeing now is many countries ­broadening the scope of their filtering to political opposition ­movements, human rights information, Web sites of minority groups, ­secessionist movements, gay and lesbian information, translation ­services, and encyclopedias.”

On the other hand, five countries—Azerbaijan, Jordan, Morocco, Singapore, and Tajikistan—that were rumored to broadly filter the Internet turned out to block just one or a few select Web sites.

ONI researchers travel to each country they test and, wherever possible, employ Internet-savvy locals who know the ISPs and cybercafés most likely to be targeted by the government. Using a Web browser in the Internet cafés, on the local ISPs, or both, they attempt to access approximately 1000 Web sites that might be targeted by any government. The sites include top human rights, activism, and pornography destinations, as well as ones that offer tools that let you surf the Web without being traced.

In-country researchers also run local lists of sites that might be targeted by the relevant authorities. In China, for example, they tried to access sites associated with Falun Gong and local democracy activists. In Arabian and Persian Gulf countries, ONI attempted to access women’s rights and Islamic dissident sites.

Testing over a span of weeks, at various times of night and day, ONI ­researchers concluded that a site had been filtered if it was persistently unavailable in the country but accessible elsewhere in the world.

ONI has noted that censorious governments have become increasingly subtle about the way they filter Internet content.

One new frontier of Internet censorship, Deibert says, is ”just-in-time filtering.” For instance, ONI detected no noteworthy filtration in Kyrgyzstan in general. But in the weeks leading up to the country’s February 2005 elections, Web sites of the country’s opposition newspapers were regularly taken down by denial-of-service attacks. ONI traced those attacks back to Ukrainian hackers for hire but was never able to establish a direct link to the Kyrgyz government.

In a more recent instance, the Cambodian government blocked SMS messaging over the country’s cellular network for the two weeks before elections last April. ”One would have to surmise,” Deibert says, ”that they were doing this to prevent mobilization of opposition, especially street demonstrations.”
