Nothing much you as a newbie user you can do.
Just try to be quiet,
seed as long as you can, avoid
hnr, and they will not even know you exist.
What is there to trust anyway,
all they have is your ip, email, and list of files you downloaded.
Even you take your own precautions in some areas, use vpn, protonmail etc, you can avoid some legal issue.
Another view you can look at is that, all the free content you get. Sometimes even old content that's dead on public
trackers.
Some top
tracker have a issue with randomly harrassing users (or other private sites) when they suspect they are stealing content and sharing to other private
trackers. But guess what, they still here and growing and high in demand.
Some
trackers are very friendly and high in terms of privacy, but they do not have content retention. Or their pretimes are slow. Or slow speeds.
Depending on your paranoia level, it is up to you to choose.
At the end you can always rely on public
tracker for the latest content. You can download from there and enjoy.
sorry for the textwall, just blabbering i guess.
