Of course, it’s a seminar topic. I’ve been working with the prototype of the Great Firewall since early 2000, at least. I was the international collaboration of Freenet, which is way before Tor. It’s an anti-censorship tool that was first released 2000, I think March 2000, and I was in charge of, for example, translating it to Taiwanese Mandarin, and also making sure that people who are human right activists use it the right way, and things like that.
