Same here. He used the key and said it didn't work. I even contacted the Humble Bundle Support but they only told me which Email adress redeemed it. Guess what, i didn't know the Email adress ^^
Anyone who might have any doubt just look at my profile and you can see that I have this profile for 6 years and never got any trouble, so I would not charge anyone if they were not guilty.
He simply used the key and without any kind of moral said it was used.
I've already asked to revogue the key and if it's possible to tell who redeemed it so I can post here his second account in a near future. Thanks for reading have a nice day =)
-REP He scammed me for my 9 steam game keys. He said that they were for a friend of his who wasn't even on his steam friends list. After he received his keys (since I went first) he said that they were duped. I looked into his game library and see all of those exact games there. After the company from which I bought them gave me a compensation and sent me new keys I offered him the same deal with him going first. Suddenly though the game that he promised to me was traded just two hours before messaging him. Overall I advice all traders to avoid this guy unless he goes first! He may act innocent BUT HE IS DEFINITELY NOT!!! I REPEAT DO NOT TRUST HIM!
-REP told me he has a Dangerous Waters key from indiegala. turned out he just took a random key he found in the SG forum (free key for some game, which already expired, and was used anyway). a shame, but this one is definitely a scammer.
