...so I just won a copy of this game in a giveaway. While activating the key, I noticed it was in a bundle with a few other games I wanted... so now I have another key, which is going into this giveaway. (Just clarifying that I'm not, in fact, just recycling the key I just won. That would be uncouth.)

EDIT: Apparently, neither explaining the situation nor opening my profile to the public were enough evidence to demonstrate that I had, in fact, redeemed the key I had previously won on my own account, and had not simply regifted the same key. For those of you who blacklisted me, your feedback (implied and stated) has been noted - after this giveaway is complete, any extra keys I get from purchased bundles can just rot, if that's the "proper" thing to do.
