Proxy servers are Actually put up for you to, gain information about what you are browsing, what you are searching, what are your social network passwords and so on.
and not for your anonymity
What they do is, before delivering the page you requested to you, they add malicious javascript code in that. which then delivers information about you to the proxy server which you connected to by stealing your cookies. Using proxy servers you expose more to the world, than without using it. :D
so if you are looking for "How to Hack the internet" do it using your own computer. or don't do it at all ;)
