I can't give it away because the key that was given was active, and the key was drawn for free.
And just link the key and the game account to Steam, and you said that the key was used on another site, so tell me how you know this knowing that when you try to activate the Steam keys, it just says "error wrong keys ", it doesn't say anything that it was from another site if you know that's because you've already activated it.
And I'm not going to give you a key that was drawn for free, especially since you told me that the key was from another site knowing that Steam never says whether it's from another site or not.
