Censorship and Two Types of Self-Censorship∗†
We propose and defend a distinction between two types of self-censorship: public and private. In public self-censorship, individuals restrain their expressive attitudes in response to public censors. In private self-censorship, individuals do so in the absence of public censorship. We argue for this distinction by introducing a general model which allows us to identify, describe, and compare a ...
متن کاملProof-of-Censorship: Enabling centralized censorship-resistant content providers
Content providers often face legal or economic pressures to censor or remove objectionable or infringing content they host. While decentralized providers can enable censorship-resistant storage, centralized content providers remain popular for performance and usability reasons. But centralized content providers can always choose not to respond to requests for a specific file, making it difficul...
متن کاملTopological censorship.
All three-manifolds are known to occur as Cauchy surfaces of asymptotically flat vacuum spacetimes and of spacetimes with positive-energy sources. We prove here the conjecture that general relativity does not allow an observer to probe the topology of spacetime: any topological structure collapses too quickly to allow light to traverse it. More precisely, in a globally hyperbolic, asymptoticall...
متن کامل#h00t: Censorship Resistant Microblogging
Microblogging services such as Twitter are an increasingly important way to communicate, both for individuals and for groups through the use of hashtags that denote topics of conversation. However, groups can be easily blocked from communicating through blocking of posts with the given hashtags. We propose #h00t, a system for censorship resistant microblogging. #h00t presents an interface that ...
متن کاملEnabling Censorship Tolerant Networking
Billions of people in the world live under heavy information censorship. We propose a new class of delay tolerant network (DTN), known as a censorship tolerant network (CTN), to counter the growing practice of Internet-based censorship. CTNs should provide strict guarantees on the privacy of both information shared within the network and the identities of network participants. CTN software need...
