You don't have any terms and conditions, privacy policy for your casino game? I think it's important to know what are the grounds the player are into and what they are sharing here especially data privacy kind of stuff. I can only see two usernames there but their avatar are clearly not the same, was that only an example?
This is what I was looking for also. Because you need at least the terms and conditions, so every player knows what to comply.
Because if not, no reference is found if someone got any issue, and they don't know what to do.
The casino also can confiscate the funds from the player without any reference of their violation because they don't have the list.
If the OP won big here, well, we can't say if he is just promoting their site or he is indeed a player on this site.
For now, it is better to take precautions as they have important features lacking.
