I'm in Culiacán, the capital of the Mexican state of Sinaloa. Part of my work here has been to investigate and highlight the cyber-attacks that the award-winning weekly local newsmagazine Ríodoce has encountered in its coverage of the violent drugs war here.
But discussing the experiences of online editors at other publications here has shown just how intertwined the Net, the work of reporters, and the drug war have become.
I've been telling reporters that Twitter's new national blocking policy was like Chekhov's gun. Its recent appearance inevitably prefigured its future use.
A founder of Mexican news weekly Ríodoce, Javier Valdez Cárdenas, traveled to New York in November to receive CPJ's International Press Freedom Award at our annual benefit dinner. No sooner had he returned to Mexico than Ríodoce's website was thrown offline by a denial of service (DOS) attack, in which multiple computers are used to flood a webserver with fake requests, slowing down the site so that it cannot serve legitimate requests.
On his blog, El Oso, David Sasaki has just finished up the third and last part in his series, "Internet Censorship and Freedom of Expression in Latin America." It's a brilliant overview of current political and social pressures on free speech and online reporting in the region.
Some key observations:
Direct governmental censorship in Latin America remains largely non-existent. Even occasional "murky," anecdotal evidence is mostly confined to Cuba and perhaps Venezuela. Sasaki does a great job of collating what's been rumored so far. The OpenNet Initiative has said it will shortly publish updated research.
Litigation over content is the most widespread threat to free expression online across the region. As CPJ has reported for many years, criminal defamation laws and overbroad judicial decisions affect independent journalism in many Latin American countries. The large numbers of ongoing cases against individual Net users and their hosting services show that this risk has not diminished online.
Brazil and Chile are leading the way in attempts to create Internet-era regulation, with broad participation. Other countries could learn a lot from watching how this new body of law develops, despite occasional missteps (or perhaps because of them).
The above will not surprise close watchers of the Latin American Internet, and it certainly fits with CPJ's own observations there. The real meat of this article, though, lies in the examples. From decades old videos of famous censored Argentine satire to a brief glimpse of the world of Mexican botnets (a collection of hijacked computers used remotely by criminals), it's a compelling and informative read. Check out part one, an overview of the idea of Internet regulation; part two, a survey of intermediary liability cases in the region; and part three, which offers a closer look at direct Net censorship in Latin America, as well as brief glances at Net neutrality, privacy and cybercrime.
