I use newpipe from the FOSSdroid repo

American here, I've torrented movies and anime for a few years now and only got one warning (For downloading "The Big Short" of of Pirate bay). I have since stopped seeding on that site, though a seed on smaller ones. I have had no issues with lawyers since.

How does one find stuff on usenet?

Sounds based. This there any comparable system you are aware of that works like this?
