What happens if the winner of a giveaway already owns the game on Steam?

We keep meeting like this

That's pretty much what I plan on doing, I just wanted clarification to see if there are any codified rules etc. I sure hope there's some way to prevent this in the future without having to manually investigate

What if the winner set his/her profile private and refuse to make it public?
Is the gifter obligated to gift the winner in such circumstance or the gifter can back off on gifting?

my understanding is the site picks someone automatically, so if someone wins and you refuse to give them the gift, then i dont think you have the option to pick someone else.

But does the point system punish legitimate users more than it dissuades the cheapskates? I think a simple and easy way of doing it would be a game check, based on a public profile. I understand the privacy issue, and respect it, but this is a public place, where you are part of a public community, so people should have to deal with it if they want to enter giveaways.

Hey CG, one of my giveaway's could do with another winner selecting. I fired off emails to the link at the bottom of the site; I'm guessing you've been too busy to check them, or the emails haven't gone through. I'll try catch you on Steam tonight if you hadn't gotten them.

Thanks for the response

The user did redeem the gift, but I have their account name/profile page if you want to flag him/her. Is there any good way for me to message them to you?

Me too bruh. I think it would be better if they enforced an "all-public profile" rule so we could check to see if winners do/don't own the giveaway game

Or, better yet, make it impossible to enter if you already own the game

I don't care about negative rep from scumbags who enter giveaways for games they already own. Their opinion does not matter to me.

All I care about is giving out games for free to people who have never played them, gifting hours of new entertainment and unique fun.
