I have email DB many time with no response over 10+ days

They even update scam thread (https://bitcointalk.org/index.php?topic=1481406.msg14931306#msg14931306) with

"We will not be discussing this matter with hungerstyle any further and require that the person who sent these double spent transactions and who owns the payout address will get in touch with us and sign an agreement if he wants his coins back."

I think they just plan to hope blow over but many people it seem see safety issue.
