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.
I think the issue is that DB is likely not following the letter of the law in operating their website. As a result I would say they could potentially face liability (probably criminal) if they were to expose the dev even if they did nothing wrong in the nonce and mateo incident.
My personal opinion on them is that they have a lot of money (maybe they were early miners and have a good amount of bitcoin to spend) but have
