Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

In several countries there are laws that let representatives of copyright holders just get from ISPs the contact information of their users on demand (I believe Germany and the UK are like that) whilst in some others there are other similars laws like the ones where the ISPs have to pass the letters from the representatives of the copyright holders to their customers (such as Canada?). In fact as far as I know these kinds of letters only exist in such countries and only since such laws were passed - without such laws it's the traditional process where a Court Order is required for such things which is way more hassle in general and thus not worth it to go after non-commercial copyright violation.

Add a VPN on the user side and suddently to track the person associated to the IP address detected sharing a specific torrent requires a Court Order (for the VPN provider to disclose that).

Use a VPN exit point in a different country and now that Court Order has to be obtained from a court in a different country from that were the user can be sued.

If in a country with extreme pro-copyright legislation like that, good luck getting enough in damages from a Court for the Copyright violation of somebody sharing a torrent for non-commercial purposes to pay for the cost of simply getting the contact of that person from their IP.
