Winners have 7 days to activate their gift, but if I spot the winner online all the time, over the course of several days, and entering more giveaways without activating this to their account first, that's a blacklist.

Please set your profile and games to public if you win, so that I can properly check ownership before giving you the key. I usually send the key within the day.

I don't blacklist for not playing the games.

To my knowledge, there are no region restrictions on this key.

You don't have to leave thank-you messages, its not mandatory, not even for the winner.
