To be honest, this post seems very ignorant of the entire scene.
How do you know where to go? You run in techie circles and online groups. You look for ways to apply to different trackers. This isn’t hidden info.
You act like piracy is one big library that needs shoring up in specific places. It doesn’t really work like that. Find a few communities you like, download content from them that you like, seed forever.
After you have built a big library of things you are seeding, maybe volunteer for a low level staff position.
But the basic take away is that piracy is fine as it is. It doesn’t need you to save it. The best thing you can do is seed and keep learning.
