and even help ourselves preserve our anonymity on the net: join the Tor Project.
Tor is a network that routes your computer through a series of proxies to make it extremely difficult to trace who and where you are. The practical side of this is that you can surf anonymously. The extremely practical side of this is that people in heavily censored countries can also post on the web and their authorities will not be able to trace their IPs.
I've been using it for about a week, and while it's a little disconcerting to see Google ads on DU in Dutch, French, or other languages, the whole thing seems to work fairly well.
The best way to get started is here:
https://www.torproject.org/ Read all the disclaimers carefully to see if it's useful to you. The best way to get started is to download the Tor+browser. It will give you a stripped down Firefox, perfect for using Tor. You can use your other copy of Firefox if you need to use the extensions and leave the Tor enabled copy in the background.
It's little enough to do to help our unfree friends.
(so far, it's not illegal, but I doubt the PTB will be amused for long)
