Internet Blocks: Three Case Studies

A study led by Héctor Huici and Roberto H. Iglesias suggests that preserving freedom of expression and avoiding any type of censorship, especially in the field of politics and ideas, should be the argument against Internet blocks in Latin American and the Caribbean.

The researchers responsible for the study titled Blocked: The Practice of Internet Blocking and Three Latin American Case Studies, one of the studies selected* by LACNIC’s Líderes Program, believe that blocking should be specific, limited to the minimum necessary, and in all cases ensure that they are backed by legal support.

Blocked. It is increasingly common for individuals and governments to attempt to block access to online content they consider illegal by using technical means, said Iglesias.

Both researchers studied cases of website blocking in Uruguay, Argentina, and Venezuela.  Based on the scenarios they analyzed, the rationale behind these blocks in Argentina is essentially the protection of third-party rights. Blocks are decided by the courts, except in cases of “manifest illegality” (material involving child sexual abuse, advocating in favor of genocide, etc.) that may result in intermediary liability if the content is not removed or blocked by the site itself or at the request of the interested party or even of a third party.

In Uruguay, URSEC, the regulatory authority, has the power to administratively enforce Internet blocks, yet it has only used this power in cases of infringement of the television rights of football matches. The procedure is subject to subsequent judicial review, but even so it has been the target of criticism by the Internet community, who believe that this guarantee is not sufficient and that this methodology might be extended to other types of content.

According to Iglesias, Venezuela had the largest number of persistent blocks, which always targeted news and political content, and almost always affected the right to freedom of expression and information. The study showed that, in Venezuela, blocks are implemented through administrative orders, often without a clear or identifiable legal basis.

Technical complexity. The authors highlighted that blocks often appear to be ineffective from a technical point of view. This is due to how easily they can be circumvented by the authors of the blocked content (by changing their location, IP address, format, etc.) as well as by the users who wish to access the content (by changing the configuration of their devices, using circumvention tools, anonymizers, etc.).

Meanwhile, from the perspective of freedom of expression, Internet blocks are often considered a violation of the Universal Declaration of Human Rights (1948) or the Pact of San José de Costa Rica (1969). However, both declarations and other international agreements, depending on the case, prohibit advocating for genocide or war, inciting to violence, and child pornography, and they enshrine the right to private life as well as to “honor and reputation.”

Assuming that blocking is the last resort to enforce these principles, it is important to stress the idea that what is illegal offline must also be illegal online. Despite this, Iglesias noted that it is not clear that what is considered illegal in the real world is illegal in the virtual world.
