Adzeth: I was referring to how before I started telling that my giveaways were giveaways, and encoded 'em with what I call Stupid Code (if you hide something in plain view stupidly or among stupidity, no one will notice), it took a while for someone to take the codes. Funnily enough, and in accordance with the law I mentioned, I hadn't even noticed that the OP had a gift code in it. :)
So anyway, being too sneaky is tricky.
Do not worry it was a redeemed code already. I did replace it with an undredeemed one, which I hoped would serve as a good example of how to use those links for newbs, but someone redeemed that one. =/ Might try again later.
DProject: Maybe add a comment something on the lines of:
"So you gifted a game, you can see if the correct person activated it and not some random dude who snatched the code somehow, by going...(I forgot where I'm supposed to go see that)"
Thanks for the suggestion, added with info from GameRager
