If you dont want to go for interviews, Let me tell you one shortcut. Get into TehC first. As you have seedbox, download some amount of freeleech movies (around 60 GB) and keep it seeding for 1 month. This is required to reach PU status (Average seeding 50 GB). When you are in to PU, you can get easily invites to BTN, what.cd and many more. Getting BTN from invite forums is the best and secure way for potential users otherwise they like to ban people even if they suspect little bit. If you get into what.cd you can get invites to most of the high level private trackers reaching to their PU status (upload 25 GB).
