Question about suspicious winner.

create a ticket and ask for a reroll. Explain the multiple wins.
Then let support decide

Note: SGTools is known to have issues with DLC, and can show false positives from time to time

Request a re-roll, ask support to verify the winner. They'll tell you if you can't re-roll.

Throw it to staff. If they want to suspend for rule-breaking, they will. If they don't, and you don't have any other reason to hesitate, send the game.

You aren't punishing anyone, you're doing your impartial duty to the site in reporting things. Whatever happens isn't 'picking on anyone', or 'denying luck', it's just a predictable outcome of their own actions, and your own respectful acknowledgement of site rules. Let staff sort it, if you don't have any personal considerations on the matter [ie, wanting to force a non-activation rather than give to a rule-breaker, or on the opposite end, not caring about the behavior obligations of participating in the site or believing that luck should be arbitrary and unshaped.]

Besides, they seem like the unappreciative sort. Think how much more satisfying it could be for all involved if you can get the game to someone that really appreciates their wins.

An additional note: If support chooses to suspend the user (because he hadn't served the suspension in the past) it is still up to you whether you want to re-roll the actual win. Once an user is suspended all wins can be rerolled at the creators' discretion.

Always request the reroll if there's something odd. If they've already been suspended, support will deny the reroll and tell you that it's been dealt with already. If they haven't already been suspended, you get the reroll and they get the suspension that they deserve.

No matter how old still request a re-roll. The worst that can happen is simply they where already suspend and the re-roll will be denied.

So how long does it usually take for a re-roll?

Looks like it got re-rolled and person suspended for three weeks.

Do giveaways done with the sg rule checker or whatever it's called count as being open or invite only? After this incident I might start using that from now on?
