The winner is ignoring me

Should I wait for 5 more days or request a new winner?

Yes you should 5 more days.

Support won't even grant you a re-roll until the full 7 days have passed.

He still has 5 days left. You must wait.

Giveaway creators are allowed one week to send the gift after the giveaway has ended.

I think it should work the other way around as well. So he has a week to accept^^ (and online doesnt mean necessary the person is "looking" - i know a lot of people who have 100+ Tabs open in their browser...^^)

I don't agree with this but it's ok I will wait and compromise with the rules. Either way he is going to my blacklist after we solved this. If he couldn't make contact with me so far he shouldn't be online either.

Yes you should wait 7 days until you ask for a new winner.

From my experience with these giveaways (4 out of 400+) the winner probably just let's their autojoin-script run and only checks once a week what games they've farmed.
Be prepared to receive some dumb comments for trying to gift the game.

Περίμενε να περάσει το εφταήμερο και, αν δε σου έχει απαντήσει, ζήτα να κάνουνε reroll.

That's how you stop making lvl 0-1 giveaways ¯_(ツ)_/¯

You can be active on the site using smartphones, PCs at work etc., whereas activation is only possible at a home PC. Therefore activity isn't a proof for intentional ignoring.

Theres a possibility he has Archi farming cards, then you look online 24/7 even if you personally are not anywhere near a pc.

Private profile aside (that's certainly an issue) you should wait. I've had plenty of people take 2-3 days to redeem a gift despite being online here dozens of times. You need to be at a PC to redeem a key and not everyone can get to theirs as frequently as you or I. Of all the times this has happened only once has someone said they wouldn't be able to redeem for a couple days.

Most likely that's the case here. He might know he has a week and doesn't feel the need to reply to you. Of course the courteous thing to do would be to give you a heads up but hey. There's a week of room so maybe he doesn't think it's necessary. I agree with you, he really should have responded, but at this point all you can do is wait.

arent private profiles against the rules? request a new wiener.

Uhh ... you can't just send him the key/gift? Why do you need to contact him first?

I have this same problem,
winner is online often, but with private profile. i tried sending gift by mail but he doesnt accept, i have no idea how to contact him, and my GA also ended 2 days ago. think we have the same person? lol

Remember to take screenshot of the emails and your friend requests on Steam (in case they are blocked), to proof to support after 7 days, that the winner is "rejecting the gift".

Ignore him harder !

He may have checked his "win message" before you sent the key. So he's not checking back on that GA because he hasn't seen that the key is now available. Instead of writing on the GA he won, try writing on a GA of his, that way he gets a notification.

In a group GA - Waited 9.5 days for a winner to accept (Also involved the mods) and the asswipe didn't even say thanks.

You always need to wait 1 week. I've been rejecting friend requests recently. He maybe just doesn't want another +1 on the list. He maybe isn't at his PC and is on mobile. People have lives. Just take screenshots and after 1 week request a new winner. Please be patient in the future.

Dude, it's a key right? You don't have to friend him on Steam to send that. Just put it on the winners page.

People are (rather understandably, given your phrasing) misunderstanding the context, so you should probably rephrase your OP, to avoid getting needless negative responses. For private profiles, you certainly can attempt to contact the winner immediately, but if can't get a hold of them (or want to avoid the hassle), put in a reroll ticket and ask support to check their library for you (as SG keeps a record of their library from previous account syncs).

You are correct in your right to contact them within the first 7 days to make sure they're a valid recipient, but you are never in the clear to harass someone, regardless of context. If at first you don't succeed [and before anything, always try to contact through SG, most of us don't necessarily check our e-mails, or as I'll note below, utilize Steam the way you expect. Likewise, that serves as first contact proof for SG support, which can be useful in expediting a no-response reroll] then just contact support to help facilitate the giveaway.

I can see him online here pretty much every time I check

Perhaps the user is on mobile, and can't check Steam.

sent to him 3 emails and 2 friend requests on steam which were rejected!

How do you know friend requests on Steam were rejected? There should be no indication either way as to if you're blocked or your previous request simply hasn't been answered yet. And lay off the e-mails- they either got it, or it's just hitting spam filter, so more attempts don't matter. Your e-mail provider will send you a message if the e-mail bounced.

Should I wait for 5 more days or request a new winner?

You should most certainly contact staff with a reroll request, just to keep them apprised of the situation. You cannot, however, ask for a no-response reroll until 7 days have passed from your first contact attempt.

From his SG profile he seems to know how the site works but he doesn't change his profile to public while he know that he won (wtf). I think no one cared so far for his profile and they just sent the gifts to him.

I'll give you this one. While some users are cognizant of what an inconvenience private accounts are on SG, and try their best to be respectful with it, the majority do seem to be.. well, the sort you'd expect to willingly cause inconvenience to others. That said, many private users prefer friend adds over profile setting changes (as that rather negates the entire purpose of having it private in the first place).

PS. He is online right now.

If you mean SG, I addressed that above; If you mean Steam, that could be a slew of things, from family members to idling to leaving it up permanently with their internet flickering on and off.

his status is frequently changing from offline to online during these 2 days so he is active and doesn't have open tabs.
If he couldn't make contact with me so far he shouldn't be online either.

These types of comments make you out to be the problem in the interaction, since (as noted by myself and others) there are plenty of reasons for such situations to occur. It's never a good idea to make too-strong assumptions based on such things. As noted, users do have a right to not be harassed, and we never truly know their circumstances. Making harsh assumption-based comments like that are only going to cause people to (rightfully) view you as having a needlessly negative attitude.

I'm personally thankful that you're taking the effort to check a user's validity before sending a game, for the good of the site's health; but that doesn't mean you shouldn't be respectful about it, in the manner you'd hope your winner would be respectful to you. :)

Winner doesn't want his game.

Wait 7 days (as per the rules), then contact the SG support and let them re-roll the giveaway.

In occasions when i need to deliver myself, I usually follow a very simple checklist:

1. I'm contacting the winner right away in every possible way: email, friend-request and a note on his profile, informing him that he's won and i'm available for the delivery here, there and there. (On this step, i might take some screenshots, depending on the winner's level and his steam profile longevity).

2. I wait patiently, i restrain myselft from searching him elsewhere or checking his status. All these actions don't really matter to him cause he's either far away, really busy with something more serious, or a total dumbass. Now while saying that, taking a screenshot or two prooving his online presence during the days, is simple, painless and very recommended. Other than that is just a waste of energy.

3. On the 5th day, i send the same invitation and the same email back to the winner. Again, i wait patiently until he contacts me. If he's still a ghost on the 7th day, then ask for a reroll and blacklist his dumbassy highness. No need to worry too much for a game key though. ;)

Tip: level up your more special giveaways. ;)
