Just a quick question

Afaik, you can request a re-roll if the winner of your GA is suspended (needs citation).

To be on the safe side, you could create a support ticket, explain the situation (or link this thread) and ask if you should/can request a re-roll.

I don't think you have to worry about that person marking it as not received since s/he won't be on SteamGifts for a bit. I think you should be okay. Don't hold me to that though.

winner is suspended = reroll giveaway for new winner

The "request new winner" link is next to the original winner's email address on your created giveaways page. Just click that link, tell them that the user that won is suspended, and they will "reroll" the gieaway and one of the other users that entered the giveaway will be the new winner.

Thank you all for your help, I've done as suggested.

Have a great evening :)

I liked the idea of contacting support. That's always safe.

As far as the rules go, however, you have contacted the winner, and the winner has not responded. After seven days of no response, you may request a re-roll. As far as I know, there is nothing in the rules about a winner being exempted from the time requirement, regardless of the reason. I once had to re-roll because the winner simply never logged back onto Steam for over a week.
