Might wanna use
www.proxy.org or similar (google proxy and you'll find a lot of information, it's fairly easy to setup though if you want a fast connection you'll usually have to pay) to protect yourself if you're going to get into whistleblowing revealing info you're not meant to
Maybe choose another nickname too
To see some of the information that websites can see about you, visit
www.dnsstuff.com and look in the top-left corner - legal avenues can get your ISP to get up more information from that IP address, it's basically your unique internet address (even if it changes, IP's log who is using what at what particular time).
