I’m a big Whonix fan. It’s a little more user friendly. TempMail is a good choice. Together, yeah, it would be pretty damn difficult to backtrack anything coming from a computer equipped with that combo. TOR OS’s are free, though even they have a con or two. There are free VPN’s but almost all of them have some kind of a catch to them to get you to upgrade to a paid version. You just have to figure out which “catch” you’re ok with. Haha. TunnelBear has too many data limits, Hotspot Shield if you’re mobile, but no streaming, which, lets face it...no one wants one they can’t stream on. Hide.me isn’t bad, but no torrenting. My choice would probably be Windscribe, that one you can stream all you want to on. It lags your connection and causes some buffering but, if you’re patient enough to get past that then it’s isn’t the worst VPN to use.
