It would be really great to have either Private Internet Access or Mullvad VPN in Rewards page. Makeuseof, any plan on that?
Till that time, you can checkout these free VPN services : http://www.techspot.com/article/825-free-vpn-services/
Can I rely on that site? Coz I just commented that in my knowledge Softether/VPNgate are also good and they banned me for spam. Didn't even posted any links but just gave my opinion on what I read about free VPNs at other sites.
