yeah, the invites work, there are still unused one. But there is more porn on this tracker than anything else.
edit: This is the worst piece of shit tracker i've seen. If you download a torrent file it immediately counts the size towards your download even if you don't start it.
So if you often download a torrent file and then you change your mind and don't download anything you are going to ruin your ratio.
And no info, no screenshots or anything, there are just auto grabbing whatever they can from public trackers.
