Somethings not right.........

Hope this isn't too private where it needed to go in the private area but I've been checking one of my friends profile on HITS for a tracker and it always said there wasn't one. But last night when I was at her house, she logged into myspace then right after words she logged into her tracker. I even just ran her id number through hits again and it still says there is none. And I have used this tracker before bc my picture from my old profile (which is now deleted) shows up on it when I look at her page. And what's even really weird is that I don't even use the same computer as to when I used that tracker probably 2 years ago. But it still shows me as showing up.... which confuses me even more now bc I have trackers blocked from the code that I got from Gug!!! I have even noticed that with my other friends tracker on Mix map, I occasionally show up on there to. I have the ablock so I don't know why it does that. Ok, so my questions are:

1.) Why isn't her tracker showing up on hits?

2.) Why does my old picture show up on this tracker even though that myspace account has been deleted for almost 2 years and I don't even use the same computer!?

3.) Why am I showing up either way when I'm suppose to be blocking these trackers?
