Looking for a vpn that doesn't log traffic and isn't from USA/CANADA where they spy on your traffic without warrants. It is safer to connect to TOR through a VPN so your ISP / whoever is watching doesn't know that you are actually using TOR since the connection is encrypted through the VPN, adding an extra layer of security for the peace of mind.
You're most likely not going to find a free VPN that won't log your traffic and will refuse to cooperate with the law. If you're adamant about getting a free VPN, I would recommend Spotflux. However, you'd be better off using NordVPN, as they're pretty anti-LE. It's also only like 60 bucks for a yearlong subscription. I feel like, if you're willing to go the extra mile of using a VPN to hide your Tor use, you should be willing to spend 5 bucks a month on it.
