I don't think an identity would prove anything. IMO the programmer would likely deny creating the code as it would open him up to civil liability from dicebitco.in and potential criminal liability. They wish to stay anon and will likely not give up that anon just to feed the trolls
DB previously said he's personally associated with the developer and outing his identity could lead to himself being identified. I think it's an excuse, I don't believe there was a third developer, but that's the "official" reason for not naming him.
As far as liability goes, no court has the power to enforce a civil remedy on a website that likely isn't operating completely legally. As for criminally, perhaps on a looooooong shot. But you all do realize that you're "investing" or gambling with a (at best) semi-illegal gambling website owned anonymously, operated entirely though the internet, and only interacting with the owners through anonymous screen names, right? If your money is stolen, that's really on YOU.
You are very much correct. Legality here is nothing. If their was a rouge coder, he could blackmail Manl or have him imprisoned for operating an illegal gambling operation. Apart from being an unlicensed casino, they are also operating under an Indian domain extension. Of which bitcoin and gambling are illegal in India. Everything right down to the domain registration is illegal. And under Indian law, the owners of a .in domain are legally operating in india - regardless where the servers are located. Running a bitcoin casino is something you would certainly not do with the .in extension.
