No, clearly not. Valve doesn't take any accountability for trades outside of Steam's built-in features. The other person might just be attempting to defraud you. If they aren't following Steam's guidelines, they're unable to assist. This seems to be accurate.
He’s attempting to deceive you, don’t overthink it; the only chance of being banned would be if he has around 100 people to alert you about it, which will likely happen.
Verify his connections and account details for any suspicious activity. If you expected it to succeed, he’s likely attempting a scam. Check if Steam has the game; otherwise, he may not have it. Disappointing indeed.
He has played over 100 games, so it's unclear if he's reliable.
If it didn't work and he is genuine then couldn't you submit a ticket to steam or wherever u got it asking for a new cd key? I assume there is probably a key generator that works by now - assuming he is telling the truth?
Ugh, you messed up again. And your iPhone is acting weird. Auto correct? Not working.
