That is kind of dooglus to help you out with this, I only wish for your sake that you had contacted dooglus in the first place to escrow your trade between you and the scammer (he probably would have).
I have added an escrow function to Just-Dice now. See the FAQ tab for details - search for "escrow" in there.
I guess a not enough educated support person can create bad press pretty quick.
Apparently the support person was parroting the official company policy. xploited (CLAM dev) tells me he spoke to bittrex-richie (the real one!) who told him that their lawyers won't let them comment on whether they control particular crypto addresses or not. Which sucks, but at least it's not the support person's fault.
