Repeat after me... it is unrealistic to expect privacy when using the internet... repeat after me ... it is unrealistic...

Just remember that proxies aren't magical; they simply add extra hops in the middle. Each person still has an address (you, your buddy, and the pizza place). So don't think of it as "hiding" or "becoming invisible"; this isn't how the Internet works. The Internet needs to know your exact location or else you can't use it. If you were truly hidden, nobody would be able to bring you the stuff you asked for -- whether that something was a pizza or an email from a friend.: http://dmiessler.com/study/hiding_your_ip/
