The users at hackforums are terribly incompetent. These kids all run their command and control center on their local computer. The RAT has one (or several) free dns name(s) embedded and the user keeps updating those with his home ip to receive connections from them.
How hard would it be to launch an investigation into this ip address once you find it out? Would filing John Doe lawsuit allow you to do discovery on those ip addresses? Does 'an ip address is not a person' prevent you from further investigating who the actual person was?
