keys :)

I prefer giving keys, I find it more convenient for both the giveaway creator and the winner. Might be just me though.

Definitely keys.

Keys, yes

Keys are easier, you just need to fetch them once, and your winners can quickly activate them through the redeem button in the won page.

Gift links used to be considered safer, but it's no longer the case, since according to Humble, customers with the habit of sending gift links to several "friends" are considered "active resellers", and denied any form of support (if not banned altogether).

THANKS!!!
