Are you 100% sure about that first part? I'm really apprehensive about unlocking early via VPN so I think I'll just wait it out. I'd love to play as early as I can but I'd hate to get myself banned for something so insignificant.
And to take it one step further, if you were to get banned for doing something like that, what exactly happens? Do you suddenly have no more access to your library? That would be pretty crazy...
Zero reported incidents of Valve ever taking action for people using a VPN in this manner.
Why would Valve hurt a paying customer?
