This was very useful I’ll look into usenet, VPN torrents and seedboxes.

As you mentioned you simply download torrents using a paid VPN eg surfshark, nordvpn etc. Is that enough? Does that work without causing any problems with authorities and what not?

can you point me in the right direction? what should I be looking and searching? relevant terms etc

Sure,
To but it simply and bluntly. I want to be to download torrents and a full proof way to transfer the data.
Back in my home country (A) I can easily download torrents for movies, music, books without any issue. In my current EU country (B) I can’t as the laws are strict and what not.
I plan to use the Pi, remote access it, download the torrent media in country A and then transfer the data via scp, SSH or whatever to my laptop in country B.

How can I achieve this. what hardware do I need other than a Pi. what concepts should I look up. what networking terminologies do I need to familiarize with myself.
