Who?

They are thanking you for making this giveaway. Because you will be giving the game to the winner.

Hello! You're obviously new to Steamgifts. When you create a giveaway like you just did with Cities: Skylines, you are supposed to GIVE the game AWAY. Everybody is thanking you because they expect to win it from you. Please be sure to read the FAQ before further continuing to use this site.
And you might want to delete your giveaways, creating giveaways and not giving the game to the winner will result in a ban.

Ninja, você criou um sorteio e deveria dar esse jogo. Sim, você deveria dar o jogo.
Como parece que você não tem esse jogo, deveria apagar esse sorteio para evitar de ser suspenso.

Se você quer ganhar Cities: Skylines, deve entrar em um sorteio que outra pessoa criou (e que vai entregar). :)

They winned big time! You can has win too! Just read FAQ and be a WINRAR!!!
