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?

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.
