That Instagram profile no longer exists. But even if it did, who knows if it's even true. You can claim whatever you want on this forum. If you intend to deceive someone or cheat them out of their money (assuming that's the goal of this casino), you would probably be trying to hide your identity and lying about who you are.

Have you tried contacting that alleged owner to see what he says? I kind or remember that you said you did in your previous posts.
