Which Websites are Censored, Anyway? Zachary Weinberg zackw@cmu.edu Carnegie Mellon University 17 July 2014
Sources • Herdict , 2009–2014: 65,000 URLs reported as inaccessible (not necessarily censored) by users worldwide • Citizen Lab , 2014: 10,600 URLs in synthetic list intended to probe for censorship; 2014 • Per-country lists , 2009, 2012, 2014: eight leaked or reverse-engineered lists of URLs and/or sites allegedly censored in those countries. Collated by bpjmleak.neocities.org
Mostly not the usual suspects Herdict (2009-2014) Thailand (2007; Wikileaks) Alexa rank CitizenLab (2014) ≤ 100 Germany (2014; BPjM hashbusting) ≤ 1000 Norway (2009; Wikileaks) ≤ 10000 Russia (2014; rublacklist.net) ≤ 100000 Australia (2009; Wikileaks) ≤ 1000000 Italy (2009; Wikileaks) unranked India (2012; Anonymous) India (2012; Assam riots) 0 10000 20000 30000 40000 50000 60000 Herdict (2009-2014) Thailand (2007; Wikileaks) CitizenLab (2014) Germany (2014; BPjM hashbusting) Norway (2009; Wikileaks) Russia (2014; rublacklist.net) Australia (2009; Wikileaks) Italy (2009; Wikileaks) India (2012; Anonymous) India (2012; Assam riots) 0% 20% 40% 60% 80% 100%
