Its some kind weard scamm. I have valid cs:go key (i know that, becouse i got it right with other 6 keys, and there was fine). She gives me money first (!), but when i give her a key she told me that its invalid (we even view it by teamview. I make a refund with Paypal. Then i give used key, but which work yesterday. It was invalid again, insted of duplicated. So i think it was steam block, prevent guessing keys (if you try activate too many wrong keys in short period, steam blocks you about 30-60 min, so even you write correct key, it still be shown as invalid). So i tell again later, but she has cs:go in her library. She told me that she trade it, and my key is fine. But when i try key on other account, it was duplicated. So she blocked her account and stole my key. She was the only one person with access to this key. Sorry, for my english.
