[Greenmangaming] Only sell region-restricted keys. Plus questions.

Most of the us and eu key are not region locked anyway .

I had the same issue with Metro Redux but fortunately I found out that the key was region locked (as you can see here) before the end of the giveaway so I just deleted it.

1. Ask support to change the game, and give that game to winner, if he agree with that.
2. Yes,delete them, no one will blame you
3. No, sorry

1. You could also see if you can trade for a copy. Or just give him another good game and ask him to agree to change or delete the giveaway. You could also agree to get him this bundle next time it's on sale instead. They will be able to change it to "received" later.
2. I'd go with better safe than sorry. Unless there is a way to check? If somebody who already owns the game, tried to activate it, would they just get the "already owned" message anyway?
3. Have heard of this issue before. Quite a long ago too. CarlEric had it. Here is the paste (he still keeps the link on his profile page).

I had the same problem with my first private giveaway (March). Solution: don't make giveaways for gmg keys. Or you can check steamdb before making a giveaway. If that game has some region-restricted version, surely that is what you bought

Sorry to hear about your problems. GMG have been selling region locked keys for some developers/publishers for some time. It has been in their FAQ for a long time that they offer no guarantees that keys will work outside of the region of the buyer. And unfortunately they offer no clue as to which games are region locked and which aren't.

Thank you guys for the solution.

1. I love how you guys suggest me how I can ask supports to change the game. I think that's the best I can do.
2. I'll have to delete them then.
3. Seems true.
