Getting into the best private trackers is not easy and it can take over a year to get into the best websites.
Whatever you you do, Do not join IPT (or the 5 websites owned by the same dude). IPT extorts people for money and has attacked other torrent websites.
The easiest way to get into the best private trackers is to take the IRC interview for red (redacted) and then you have to contribute to the website to gain user ranks. Once you ranked up your account by uploading new torrents to the website, you are given access to a recruitment forum to other websites. There are guides on the website on how to upload new torrents.
RED is like the new What.CD . RED is for music. PTP is for movies. BTN is television. These website have like an incomparable amount of content to what is available publicly. Each website has like 4+ petabytes of content. The top filesharing groups upload their releases directly to these websites.
The people who run these websites are mostly redditors and there is a subreddit ( /r/trackers ) for private tracker news. There are also guides on 4chan (yuck, I know) on how to get into private trackers. The private tracker admins hate 4chan.
I know it sounds ridiculous and a waste of time. It is what it is. It's made difficult to join because they want to maintain a community that promotes sharing.

how do you do fellow pirates
