what i read on a different forum was that he got scammed by one of his own users and his own community donated to get him back out of the red and continuing the site operation. I think when your own community trusts you enough to donate to you to keep your site going, it speaks volumes about the person running it.
the owner said he was trying to restructure the site for more security and features, but I'm not a dice roller so that's about the extent of what i know about that site.
He didn't get scammed, he just chose to do what some consider the right thing. Someone won a shit load of BTC, and the owner manually withdrew something like 1300 btc and forgot to zero out the persons balance. That person kept playing with the balance still there, lost it all, and the 1300 loss if it was real coins should have gone to the investors of the site, since it was not baked up by coins, and the investors were anticipating having a 1300 profit, he took his own coin and made up the difference.

And to the OP, yes its a legit site.
