I am previously public tracker user. And since deminoid is down I have to switch to private tracker

I want to ask what is passkey concept in private tracker? When I download a torrent file from privatetracker can
I give it to my friend to seed for me? How does the tracker know that the uploader is me?

I can't find a suitable section to ask it so post it here. Please move it if I am in wrong place.

listen bro , every account has a unique passkey , so If u gave ur friend the .torrent file , he can leech/seed without problems , but some trackers have restrictions ....
If the friend is not from the same country , or has another ISP , so u might get a problem ...
but most of trackers allow that u can leech from more than an IP
If u got any problem , talk to the staff and tell them that u r leching from your work connection ...

You used to hit and run,its easy on public tracker ,but not on private

Just do what all other member do ,seed as long as possible,try to have good ratio,and you will not have any problems .
