Aningan: They are doing exactly the same thing GOG did when they let you chose your own location when buying Witcher 2. And GOG got sued by their publisher because of it and were forced to implement real geo-location tracking.
Personally I'm against publishers who want regional pricing and I'm pro-GOG and pro-Amazon in the way they handle things. When the alternative is offering you €1 = $1 prices (or not at all for some regions) I'll take their turning a blind eye and giving you the fairest prices they can, and I'll thank them for it.
I do understand they're allowing you to do it, however there's already been cases where people's support was simply refused, simply because they lied about their location being in the US.
Sure, you can get the games cheap, by lying about it, but being without support alltogether because of it is not a good thing.
