Good old "sorry guys! we've been hacked" won't work here. Either the operator will disappear with funds, or he'll pay the player promptly. I hope for the latter. "Good" thing, from operator's point of view, is that bankroll was crowdfunded, so the investors will bite the loss (especially those on 10x kelly). So if owner had only small own investment (and set at conservative risk option) then there's no really a reason to make a run (assuming site is solvent).

ps. anyone knows whether huggermugger is active on bitcointalk?
