that's fine.

the only requirement is that you activate the game you won to your own account. If you acquire another copy, you're free to gift it

You can perfectly giveaway any game you have previously won, but never your win. This one must be activated in your account. If you get countless copies of the game in the same day or later, you are fine to give them away.

The two above answered the question, but now I'm wondering...

How would SG know whether you activated the key you won, vs. the key you just bought, especially when it's such a short timeframe like this? Would the system be alerted to the same key coming through the system again?

I have done that many time, completely fine. You just have to activate the copy you won in the connecting account, any seperate copy you acquire later is unrelated. Though maybe wait a while before gifting the second copy, just to be sure.

You are required to redeem any game won on this site to your linked Steam account. Any giveaways you choose to make for that same game or DLC are irrelevant.

1. You have until the end of the Grace Period to activate your win and sync your account (so it shows up here on SG).
2. If you were to activate exactly the same game/version/DLC/whatever using a key other than the one you were given, we would be able to tell.
3. Should a problem later arise with the key you won but passed on to someone else, you would have few options. It is therefore safest to simply activate the key you were given.

I suppose you got your answer; I did it too by the way. And thanks for the GA!
