Since there is one month delay between the domain going down and the payout, I've already started a private investigation which I will make public and provide to exch to help filter out cheaters before they pay anyone out.
If you don't rely on matching wallets and such, how can you prove the existence of alternative accounts? Just the words "it seems to me" and "I think" do not work as evidence on the forum. So if you started your "private" investigation, please bring your findings to this thread, and not just as a volunteer detective of alts for the exchange.
