He has a lot of alt accounts. Currently I have already spotted 19 alt accounts of this scammer including this one. To check details, you can view the following screenshots:

Please do not trust his trades. He is a CD-key scammer . He has stolen games with over $100 value from me. If you are interested, you can check the reputation report I made at the following link:

Hello, I would like to ask if you trade humble bundle cd-keys, even if you do not trade them, I am looking for a few old bundled ones, so you might have a few and I'm ready to offer some games from your wishlist, in case you are interested - accept my friendship, I'm also ready to go first if we find decent trade for both of us, thanks
