Hm i didn't know where to post this. Maybe it was even mentioned before but i didn't see it, It can help people seeking access to this traceker, its not big news or something for new thread i think so i decided to mention it here.
I heard reports of some people who recently successed to enter tracker this way. Its all about interview at IRC. You come at IRC, they ask you few questions and if you pass you are in. Here you can find more info:
