wow, that's quite some list, you should probably have made the giveaway region restricted. Anyway, thanks for the warning

Thanks a lot! :D Happy Holidays

Translation:

This key is not available in the countries listed below. If the gift recipient is in one of these countries, they may not be able to redeem the key.

That's too many countries. I recommend deleting this giveaway before it ends and make it region-restricted. It doesn't help that the warning is in German either, too many will not understand it and probably will enter anyway.

Thank you kindly.
