There's another scam accusation thread linked to in this thread but it might be worth opening another or OP adding to that one. Hard to tell whether the owner took Bestmixer's death as a convenient excuse to scam or whether he was properly spooked. If he was spooked then I see no reason why they couldn't honour withdrawals over a longer period even if they were in hiding so it's probably the former.
Getting spooked is no excuse for not processing withdrawals, or in this case mixes.
A few days ago when the Livecoin fiasco was unfolding it became evident that the exchange was operating in a way where it was (and still probably is) impossible to sue them or get any real person's data behind the exchange. Does anyone know if it is the same issue with Bitblender? Or any of the mixing services for that matter?
Is there any possible recourse for guys that are pinched for bigger amounts than OP's case?
