I doubt that you will receive any reply from them by posting a message here. It's clear that they are now dodging the issue since they already stopped their long active signature campaign and their official bitcointalk account is inactive since April 13. It's either they will abandoned the forum promotion or they are just preparing necessary document to counter your case. Because paying you is the easiest way to deal the issue yet they let the issue escalated without any official statement from them.
Let's see if they will come back and choose between the easy or hard way on dealing with their issue. One thing is for sure, Your case is valid but we can’t do anything to recover it since coinplay doesn't care about their forum reputation.
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.
Nope, there is a lot of same case like this in the past and the most notable casino that encounters dispute that ruined its reputation Betcoin which is now back again after clearing all the dispute that involves their casino. Even 1xbit reputation can be restore if they only fixed all the pending cases against them. Neutral trust is just inevitable on their trust history about the issue but this good compared to a negative trust plus active flag.
Coinplay has their own reason to not pay the user because they knew that they are right. It's not their intention to scam someone because this is their only active scam accusations that has a valid proof and the money involved is not even enough to make them bankrupt. It's all about pride and sticking to their principles are the reason why this issue escalated.
