Sockpuppetry, or manipulating online discussions with the intent to distort, has existed in online spaces for years. OTF previously supported efforts to detect these actions in online forums. Now, a variety of advanced techniques regularly employed by repressive governments allow them to manipulate and control online discourse rather than simply block the underlying medium. For instance, in Vietnam unknown actors successfully silenced those expressing dissent against the government by coordinating use of the “flag as inappropriate” function on Facebook, which, with more than 25 million users, is the dominant social platform in the country. This episode highlights how these types of tactics can not only deter freedom of expression but also silence it entirely.
