I m registered under a private torrent tracker,
Is there anyway i can hide my download status from them, so as to maintain my seed ratio
Check where you registered.
torrenting com
They do not provide any info
I have heard about non traceable torrenting, is it possible and how?
I deeply regret not being able to help much with this matter. I’m new to torrenting stuff from the web.
Actually u can’t Private trackers are private for some reasons 
Your account is linked with a unique ID when u download stuff from private trackers… You can’t bypass it. they will always know how much u have seeded and for how long.
.
If you don’t want to seed, use public trackers without any account
