Hello JingShing.

I'm just handling the ticket to delete the giveaway of "Shotgun King: The Final Checkmate" which you had won but couldn't redeem due to region restrictions of the win that weren't properly setup on the giveaway.
The creator of the giveaway asked you to just take the key and give it to a friend of yours to then mark the giveaway as received.

Do not ever do this! It's against the site rules and will get you suspended for not activating a win. If a creator gives you a key anyways and the giveaway is deleted, then sure, do what you want with it. But you can never mark a giveaway as Received if you didn't actually get the correct game (AppID of gift and game in giveaway have to match). Again, doing so would lead to suspension because of a not activated win.
What you have to do in this case is either not give feedback at all and give permission to delete or reroll with a comment on the giveaway if it's within 7 days of the giveaway ending or mark the giveaway as "Not Received" if the giveaway has ended 7 days ago.

If you haven't done so already, please take a moment to familiarize yourself with our FAQ and Guidelines.

Have a nice weekend.
