Recently I came across this hidden tracker. I tried to open it with tor browser as they said, but it did not opened. So I was assuming it might be dead. But when searching at google, I read somewhere on the forum that tracker is live but they have stopped its publicity.

So Does anyone of you came across of this tracker? What content they might offer?

Last post from 2011? I think this one is long dead.
