I sure wouldn't trust it.  He's insolvent until (if) the thief gives the funds back.

I've also wondered if the c-cex admin is dumping the DRK he was given back by the thief to covert to BTC.  I say this because only my (small) BTC balance at c-cex was ever frozen.  My DRK was not and I withdrew it immediately upon waking this morning.  But then the c-cex admin was given 10's of thousands of DRK by the thief.  If he has enough DRK but needs BTC BADLY, it makes sense he may liquidate that DRK.  I asked him and he did not deny (or confirm) it.
