HeadphonesON: I feel sick to the stomach, I've been scammed by GOG user justaquickie out of 7 games.
I can't believe I didn't use the search button before hand.
Azrael360: I'm really sorry that it happened to you. That bastard is just a lowlife scumbag loser (and high chances that is also a nobody in real life) who has got too many luck with his hoaxes for far too long, thanks to the misinformation and carelessness of many and the no help from the GOG system administrators, who have the tools to know who he really is and from where he is logging in, but have done nothing to prevent this. They don't even close accounts for confirmed scammers, which would have prevented this very issue. They only use the lazy answer "scammers can create more accounts", but obviously they can do more than that thanks to the unused logs in their servers.
If the traded games are from GOG, at least you can ask to support to void those games if you explain with proofs what happened. And if they are from Indie Gala, you can know from your account who on Steam has them now. Anything that could help to identify the culprit can be of use to report him/her on Steam.
I do feel the GOG.com staff can do more, "scammers can create more accounts" really isn't acceptable in my opinion.
Unfortunately the games were gift links on Humble Bundle and there is no way I can find on the Humble Bundle website to see the user id of the scammer who claimed the links, I have contacted the Humble Bundle support team and I'm hoping that they can help retrieve the keys back from the scammer.
