You must have been a good friend to have taken up your friends case up to the scam accusation board in filling a report, but the mistake here is that you would have referred him here to personally engaged on this by himself, it could be more suitably administered, secondly, duelbit is a gambling platform which we know of high reputation over this platform, then why should you see this as an ordinary occurrence without taking a look on the other end, if or peradventure your friend did some things wrong which he couldn't explain well to you that led to his account suspension.
