You should check your won games here. If you did you would see you are the lucky recipient of this very game. All you have to do is activate the key on your Steam account and mark as received.

Thanx!

Thanks for the Chance!

Thank you

Regifting will lead to a ban, delete the GA, and read the faq!

Why not just have a "Flag this Giveaway" button? And have some reasonably low number of hits on the button before a GA gets automatically removed?

Reported and blacklisted. I hope you get banned :)
