You guys might remember HufflePuff. In 2014 he managed to win more than US$1,000,000 from Primedice by taking advantage of its flawed client-server seed pair mechanism. The trick was later discovered, but HufflePuff refused to return the coins and his identity remains hidden to this day.
I managed to get in contact with him recently.
i don't think so if you can contacted him, i mean of course he will always "hiding" in the shadows, never showing to other people if he's "hufflepuff".
That interview looks fake, Have you other proofs if you were interviewed with him?
