LoL!(not the game,I mean, yes the game,but not LoL,but LoL!)

I've recently created a giveaway, and, guess what, the winners got the game already twice!
I know that this very game isn't the best I could give away, but it had mainly positive reviews on the moment I bought two copies of it...
Why are these guys here and how the previous contributors gave them their winnings?

EDIT: I checked other participants and they are all cool guys ,except one who won that game 1-2-3-4 TIMES already and was looking for a fifth =d
