We have promised to make a new list of proxy sites that could be used to surf (even to here) without the filtering and prying and so we are checking our list of the summer of last year. We are using webswoon for this, a great tool because you only need to make your links in a textfile and than get the screenshots.
But some things are already evident
a whole lot of these sites are gone, for sale and parked or just a pseudo search engine like information.com and other stupid stuff like that.
another thing that is evident is that on those list there are a whole lot of of those that try to download stuff to your computer, which is not really safe and if you are looking for a proxy it is because you are concerned about your safety not only your privacy
well about proxies and safety, you will have to remember that you never know who is behind that proxy and who logs what for who. In certain countries everything has to be logged and everything can be demanded by the police - with or without a warrant.
