Im very paranoid about getting into piracy and im not sure if i should or it or not but there are so many things i want that i cant afford.
is there a secure linux os that i can use without a vpn? im pretty use to windows 10 but i was told linux mint is good for this kind of stuff, is that true?
As others have said, you OS is irrelevant. Windows would be no worse in this instance.
Instead, use a block list with your torrent software. Something like this: https://github.com/Naunter/BT_BlockLists/
And remember to keep it up to date.
I consider blocklists snake oil, anyone can still get your IP just asking the tracker for a full list. If they can connect to you or not is almost irrelevant at that point.
