while I do not know anything about torrenting. "mullvad" is a highly recommended vpn providers with a strong emphasis on privacy.

This will be an unpopular answer but I use Nordvpn mainly because during Black Friday sales you can get it essentially for free using a cash back portal. The start of the sale last year, which I missed, was offering over 100% cash back. They’d pay you to use it!

Others are better but if the level of protection you’re looking for is “Comcast stop sending me piracy warnings” this’ll work.

I have a lifetime subscription for Windscribe, so I've just been using that with no issues for years. I've recommended it to some other friends and they've been fine.

I also pay for Proton services, so I have ProtonVPN, but I've yet to try it for torrenting.

Google Fiber.

They don't give a fuck.

Astrill. It's not cheap, but it's excellent. And works in China and other countries with strong internet blocking capabilities.

Mullvad or IVPN. Some VPNs like Perfect Privacy do leak your IP via DHT and other torrent features, even when full lockdown mode is on. You can search 'torrent leak test' to verify yours doesn't. I found out with a 2nd DMCA warning from my ISP.

Is a VPN even worth it for that use case? A seedbox won't cost that much more, esp. if you factor in electricity costs from keeping your machine running. And getting to 1.0 seed ratio is also much easier.
