Hi everyone! I'm new to private trackers and while i've been torrenting for a while with YIFY i heard thatprivate trackers have better quality torrents but i've wondered a few things:
1) Do you have to upload torrents to private trackers or can you just download them? I've read all the tutorials but still don't get what a ratio is and how that relates to uploads and downloads.
2) How do i get an invite to a tracker? It would be great if there were free invites to trackers, especially those focused on cinema.
3) What can get me kicked out of these?

Thank you very much!
