-REP. User gave me a used key for Soul Axiom and blocked me on Steam.

Very unfortunate experience with this user. He seemed friendly and fair, and the trade worked out well. He knew I was not going to redeem his key immediately, and offered me a new one in case I had any problems.
However, his key ended up being a duplicate, and when trying to contact him 10 days later he had blocked me on Steam.
I know that sometimes mistakes can happen, but blocking another trader is a clear indicator of bad faith and unwillingness to comply.
