Right now it's too late to play him. Even if Coinplay pays him today, the reputation is already ruined because the attempt to scam is already done.
I could be wrong to assume this is in thier mind right now which is the reason for not coming back to reply. But it's also just a small amount that it come to this already. Such a waste they have built this casino.
I don't think so. If they pay the user, the case will be resolved and their reputation will be gained. It's hard to say that their reputation will be like previously but they won't be called as scammers.
In addition, if they agree to pay the user, it means they will have to pay for similar cases in future if they don't change their ToS. It's hard to say because we don't have internal data from Coinpay to judge their conclusion and so far, only the user provided evidence that supports his case.
The case only can be resolved if Coinplay use meditators to check evidence from Coinplay and handle the case. So far, they are not ready to do this.
