I've just tried trading with LoMNOMNOMDeer for a FOTUS armor for my Limited Edition Map pass. I knew it too good to be true but I bit on it anyways since I have faith in people but as soon as I sent him the code he says " You used it already?". Sigh.
I would've just given it to him for free if I had money but alas I'm jobless right now and had to sell some of my stuff to buy this game. Sorry for the blogfaqs, but I just wanna share it with someone and warn people out there for scammers. Sigh.
Here's a picture of my Download History as proof that I didn't redeem it. http://i.imgur.com/A7tls.jpg

Was it a new user on here or someone who has been on a while. Did you check the karma rating?
That is a shame what happened to you but at least you have learned a lesson - never trade something that is valuable to you to a stranger. Or at the very least, have their code first, try it. If it works then trade your code.
It is difficult doing this because someone has to make the first move.
