No.

The only way I think this will be ok is If you win Rift, because it is only 30days.
So i will let it in inventory until i finally begin to play. ( but it has to be in a timely manner not letting it unplayed for months)

Well,you have no reason to do that,it's not okay.

No, you are obligated to activate the game you don't have permision to regift on site, gift on another site or to a friend or to make a trade, if you won you need to activate game

If its not added in 7 days you can be suspended.

no, you don't store the won game in your inventory. it's gotta go to your library

I just do that with the first game i win: Torchlight, i just like to see it in my inventory :3
BUT ... yea, you should activate it when you receive it ^^

suspended 5 days for this .. :B haha

Nope.

I apologize for all the useless responses you received up until this point. Most people here don't know how to look into anything and just let the stupidity dribble out of their mouth.

I can see that you clearly activated the game you've won and I assume you're asking since the person who won your giveaway has not activated Baldur's Gate. You should contact support through here and inform them if they have not activated within 7 days.
