The cash out was made via blocktrades through their Dana account. I'm assuming the hacker made a quick new account to cash out the funds. Contact blocktrades and ask him to not allow Dana to exchange any more funds. If this person tries to cash out via an exchange, they'll he busted anyways so blocktrades is their only hope atm. If possible, somebody could make a script and blacklist all accounts with transfers made by merej99 and this would allow blocktrades to cancel all trades initiated through merej99's funds.
