@vastlol This is very simple and you should apply this to pretty much any other content.
In your opinion: is getting a 60$ game for free legal or illegal?
Plutonium itself is legal and won't get you in trouble.
Torrenting a paid game for free can get you in trouble.
Either use a paid VPN that supports torrenting/P2P and configure it properly or buy the game on Steam.
If you do that you will not get into trouble.
