I don't know if he had seen this profile before he deposited and played at Coinplay or he found it after he have been scammed by the casino. If he has seen this profile before, where there is so much negative feedback, he should not have deposited in that casino.
I'm sure that he is not aware of it prior to depositing there's a notification of warning on that account he might have found Coinplay on other platforms where Coinplay banner is being displayed or there is someone promoting it on other platforms,
In finding a place to report what happened to him he sign up here and posted this accusation, he did the right thing when people search for Coinplay on the internet this topic will come out and this will warn gamblers that they should not play on Coinplay because of many unresolve issues.
