Somehow I've gotten dinged several times by my isp while torrenting behind a VPN. I'm not sure how it is happening because I am disciplined in my use and all the apps related to it will only function if the VPN is up and running. It's almost as if there's something in video file itself that activates outside of the VPN somehow. Or if private internet access is not offering comprehensive protection any longer.
It's a setting in private internet access that restricts apps that you set to communicating only through VPN. If you are not connected with the VPN, the apps will not function. Kind of like a app specific kill switch
That's basically split tunnelling which is not what I'm referring to. In my case I use qbittorrent, and in the advanced settings you can make it only download through a specific network adapter, which is infinitely better than split tunneling. I recommend you to try that!
It is owned by an advertising company, the same as expressvpn for what I now, so I dont trust it...
Edit: I checked, PIA was aquired by Kate Tecnologies which also owns ExpressVPN and the owner also has a gambling company. I would rather use Mullvad, because you can pay with monero or cash, but the best solution would be hosting your on vpn in a vps
