Don't really know but tracking is the same as tracking someone on myspace (which is possible had it happen to my little brother). All they have to do is find your IP address and that will lead them to your ADDRESS no bullshit. My brother was running from the cops a couple years back and I didn't really think anything of it let him stay at my house for TWO FREAKING NIGHTS, one of those nights he gets on myspace, next morning I get a call from my father telling me that the cops are on the way to my house to raid it and look for him. NO ONE EVEN KNEW HE WAS STAYING WITH ME, not even my roommates. Found out later they traced his/my address using myspace with my IP address. So ya they can....... Use a proxy on the internet they are free

Peace
