I want to share my experience of using https://invitez.net/ to get invitation codes to private trackers. This resource is a real godsend! First of all, everything is clearly and lucidly described there, the choice of trackers is very wide, and the prices are quite reasonable. The site is easy to use, and I found everything I needed there. In short, I recommend it to everyone who wants to get to private trackers without unnecessary headaches. Download and enjoy!
