We consider the question of strong cosmic censorship in spatially compact, spatially locally homogeneous vacuum models. We show in particular that strong cosmic censorship holds in Bianchi IX vacuum space–times with spherical spatial topology.

Censorship of free speech on the Internet has been an increasing problem as the methods of identifying and filtering traffic have become more sophisticated. A number of approaches to counteract Internet censorship have been implemented, from censorship-resistant publishing systems to anonymizing proxies. While existing systems provide protection against some attacks, they fail to provide resist...

In this study, we take another look at five years worth of Web censorship data gathered by the OpenNet Initiative in 77 countries using user-based testing with locally-relevant content. Prior to our work, this data had only been analyzed with limited automation, with a focus on what content had been blocked, rather than how blocking was carried out. In this study, we use more rigorous automatio...

We present a taxonomy of Internet censorship resistance strategies and techniques extracted from analyzing proposed and implemented systems. We categorize the strategies into the following six types to form the CORDON taxonomy: Collateral damage, where the damage caused by censorship would outweigh its benefits; Outside scope of influence, where the censor is powerless to act due to it having n...

Following the enactment of computer crime law in Thailand, online service providers are compelled to control illegal content including content that is deemed harmful or problematic. This situation leads to self-censorship of intermediaries, often resulting in overblocking to avoid violating the law. Such filtering flaw both infringes users’ freedom of expression and impedes the business of OSPs...

Despite the pervasive nature of Internet censorship and the continuous evolution of how and where censorship is applied, measurements of censorship remain comparatively sparse. Understanding the scope, scale, and evolution of Internet censorship requires global measurements, performed at regular intervals. Unfortunately, the state of the art relies on techniques that, by and large, require user...

Hip-hop culture and rap music originated from the African-American community that emerged around 1970s in New York City. started to enter PRC 1990s continues grow among younger generation. A hip-hop talent search show titled The Rap of China, released 2017, became very popular, bringing fore. Unfortunately, it must eventually face government’s intervention its development.

The number of countries that censor and monitor their citizens’ use of the Internet is increasing. While it is no secret that China and Iran censor the Internet, at least 25 countries, including Pakistan, Ethiopia, Thailand and Uzbekistan, also have technical filtering regimes in place. Some of the technology is even exported by western companies: search engines, blog hosting providers and emai...
