a law company can basically send a legal letter asking your ISP
It’s the same in France, and I guess also all over Europe. Those companies mostly look at who is seeding torrents, and that’s why you can safely use direct-downloads like Uptobox (DD) or Usenet.
VPNs can fail and not all VPNs allow you to torrent
You’re pretty safe if you use the application given by the VPN, and most don’t care about torrents. Also e.g. Mullvad has a page to make sure that you are not leaking info (https://mullvad.net/en/check) and other VPNs should have this too.
You can stream movies
The article is wrong here: you either download or you torrent. “Streaming” is not a technical concept. You mostly get caught when you seed.
You could be a pedophile and therefore you don’t deserve privacy. Please post in this thread your address, phone number, and all your passwords. I’m waiting.
