I'm investigating about the theft, just talked with the dice developer that is going ti give me some proof about what happened.
I will keep you updated.

As you said bleutrade can't help us, he can't track or block the trade from a certain address.
Has happened something like that to me time ago, a coin was taken from my wallet, and I asked help to exchanges to avoid to take the coin from that address, but they can't do that.

Btw, thanks for the big support you're giving to graffiti.
