I believe there are ways to bypass ip restrictions and make it look like your from another country. Not to familiar with them myself since I've never needed to use them. Also, I've heard you need an American credit card to sign up (I'm American, so it's a non issue for me), so if you don't have way of accessing one of those it's pointless
I have a hard time seeing how Viz would even dislike that.
