You mentioned Rockstar in the giveaway description so I need to ask if this is from HB Ukraine bundle? If it is from HB then it's only for Rockstar Games, not for Steam and if so the giveaway needs to be deleted. Giveaways on this site are only for Steam games as mentioned by the SG Guidelines.

Thank you for the Giveway

As said, you have to delete this giveaway. Only Steam keys are allowed to create a giveaway in Steam Gifts. Winner can't check key as received because he can be banned for contravening Steam Gifts rules.

Warning for the winner: it is strongly advised to not declare this game as received if it is not a Steam key. Declaring a game received without having it on your Steam account can lead to a temporary ban from steamgifts (or a permanent ban if it happens several times), and also it will prevent you from entering giveaways that use sgtools.
