Jesus tapdancing Christ!
Thank you for having an exchange with security unfit for purpose and once hacked off all funds being honest and offering to sell shares. This is Poloniex handbook right here.

The exchange gets hacked and a sorry is enough? Was the exchange run for charity or as a pure hobby? No! Where are the profits now? Once again failure to invest returns in security empties the users' pockets. Oh but there's a sorry. So it's the same as Mt Gox but the admin admitted to running a shitty service
