Winner doesn't accept gift

Hi!
So there is this guy who won my Eufloria giveaway.
Well, I took a look at his Steam profile. This guy doesn't really play anything in Steam. 3.2 hrs played last 2 weeks.
His wishlist and owned games list is full of war games, I don't see why he would even want Eufloria.

I sent my gift to the email address I was supposed to send it. But he hasn't accepted it yet in last 3 days. I tried to add him as friend in Steam, he doesn't accept my invite. I see that he has been logged on because his profile says: "Last seen 42 hours ago."

Is my game going to be pending for the next 5 years if he never goes to receive it? Will it be marked as "Not received"?
This gift system is just stupid if gamers who never play or are never online or doesn't even want this game join and win.
I wanted someone to enjoy this game, I didn't want it to go to someone who just takes a look at his games list and sees another game he will never play. I only join giveaways on games I want to play. I know someone wants my Eufloria more than this guy.
