Sokwanele means “enough is enough” in a Bantu dialect. It is also the name of a Zimbabwean pro-democracy website whose bloggers last year published accounts of atrocities by Robert Mugabe’s regime and posted election-day updates describing voter intimidation and apparent ballot stuffing. You can visit Sokwanele’s “terror album” and see photographs of firebombed homes, of people with deep wounds carved into their backs, of a hospitalized 70-year-old woman who’d been beaten and thrown on her cooking fire (she later died). You can find detailed, frequently updated maps describing regional violence and other incidents. You will be confronted with gruesome news, starkly captioned: “Joshua Bakacheza’s Body Found.”

Because this horrific content is so readily available, it is easy to overlook the courage it took to produce it. The anonymous photographers and polling-station bloggers who uploaded the Sokwanele material remain very much in danger. In a place like Zimbabwe, where saying the wrong thing can get you killed or thrown in prison on treason charges, you take precautions: You’re careful about whom you talk to; you’re discreet when you enter a clinic to take pictures. And when you get to the point of putting your information on the Internet, you need protection from the possibility that your computer’s digital address will be traced back to you.
Maybe, at that point, you use Tor, one of several Internet anonymity systems that encrypt data or hide the accompanying Internet address, and route the data to its final destination through intermediate computers called proxies. This combination of routing and encryption can mask a computer’s actual location and circumvent government filters; to prying eyes, the Internet traffic seems to be coming from the proxies. At a time when global Internet access and social-networking technologies are surging, such tools are increasingly important to bloggers and other web users living under repressive regimes. Without them, people in these countries might be unable to speak or read freely online.
Unlike most anonymity and circumvention technologies, Tor uses multiple proxies and encryption steps, providing extra security that is especially prized in areas where the risks are greatest. Paradoxically, that means it’s impossible to confirm whether it’s being used by the Zimbabwean bloggers.
