Question on how scams are handled in certain cases

So I'm going through my first scam, and I understand Rule 5 and I'm not looking to solve that here.

What I'm curious about is, how are scams/refunds handled when a person is figured out to have scammed every person who bought into something of theirs, but the person wound up not winning.

Here's the situation and I'm simply asking about how Whatnot handles this - I bought into a basketball card game where you paid $X and then they flipped a basketball team card over, and if that matched the card on the table's team, then you won that card. Let's just say it averaged out to 1 in 6 people would win per purchase. I wound up winning, but the seller has never shipped the item or responded to messages, so I know that it was a scam. For the 5 other people on average that lost, they won't know that.

Will Whatnot reach out to those people that got scammed and reimburse them?

I'm nervous that they wouldn't, but that wouldn't be right considering it was their platform who allowed these people to sign up and sell on there.
