Because people can actually buy legit gifts of this game and give it. Instead of getting it on iphone. The guy who is doing the giveaway didnt actually pay for the keys that is why it is against the rules. Not to say that I wont be entering. lol good odds of winning and don't own an iphone.

Its not forbidden, don't get me wrong here. Its just the exploited serials you can get for free through an iPhone game are not welcome here. 10 copies look quite suspicious to me.

I've done it as well but the Moderators on this site were talking with the DEV's of eets and figured out they will restrict such giveaways. Single copies -> Yes, Multiple Copies -> Explanation please
