GameRager: They still can't track if you're the one behind 2 separate accounts if you're careful enough. It's like you think they're big brother wiht eyes everywhere with how you describe them. 0.o
You'll have to trust me on this one. But they can indeed track them. I know this not just from the above example I gave, but also because I used to be a part of their translation team (with another account on a completely separate IP address).
The simple point remains, if you you are at all concerned over losing access to your current games on Steam, steer clear of CD keys like this one for which you cannot guarantee that they are not stolen/paid for using fraudulent transactions, etc.
