I submitted articleak, which something very similar a few days ago, but it didn't get upvoted. Maybe people on Hacker News do not like Tor?

The idea of using Tor is that the site is way harder for authorities to get down, and even if they do break Tor and get to the server, the users will still be entirely protected (there can't be any information about them in the logs or anything).
