You haven't heard of Tor before or something in that article about Tor?
Don't mean to sound like I know more than others but I thought Tor is big around the world. First heard of it many years ago, used it for a week or so but really not that paranoid about privacy to go through either being a user or make become a server.
My experience with it was it works but slower much like proxies. It's been used and abused in the way you would expect from something like it.
