about region restrictions

No, mark it as not received. Marking it as received will only give you trouble since it will be as if you had received but not activated and regifted, which is forbidden.

The creator of the giveaway broke the rules when he created a giveaway for a region-locked game.

Read FAQ, regifts not allowed.

Per the FAQ: "Do not submit CD-keys or Steam gifts that have regional restrictions, or those that require VPN activation or methods to bypass regional restrictions."

Wait for 7 days, then mark as not received. After all, you didn't get the game you won.

Ok, thank you for your comments and suggestions. I will send back the gift and tell about the situation to the giveaway creator.

how can you mark it as recieved, if you didn;t get the game(you have to redeem it in your account)

Morrowind!

Sorry about changing the subject, but I guess it still matches the title:

Do anyone know if the gifts from south america are still being restricted?
