This kind of people should be banned on playing in any casino or gambling platform. This brings more trouble than profit to the gambling industry. Not only they are blaming Casinos for the losses, they even put a lot of effort in defaming the platform where they got their huge losses. We have seen several cases like this in the forum, even filing a scam complaint on the casino platform which at the end is futile because they have no evidence in hand, and the thread is created due to hate and unacceptance of losses.
We must keep balance in our thinking. With any scam accusation from a gambler against a casino, we must wait for a casino response to see how true the accusation is.
It is more easily for a gambler to file accusation against a casino with their screenshots of proof.
It is harder for a casino to show screenshots of proof because as a business they have agreement and responsibility to protect user privacy including personal information. However, they can show some proofs that don't break their Non-disclosure agreement but still enough to confirm a scam accusation from a gambler is invalid (lie).
I feel like as long as there is concrete proof of scam just from one side, then the topic is basically done, no matter what the other side shows. For example there is another scam website, I am not going to name them because they may neg rate me, but we all know them, not rollbit, rollbit is legit if you ask me. That website always kept on saying the gambler ended up doing something against the rules, but they did this to dozens of people eventually and got neg rated. Because gamblers provided proof, one side was enough there.
So as long as you can provide 100% guaranteed proof of scam, then the casinos can't do much about it. Every gambler needs to provide 100% sure thing proof, that way there is no need for casinos to provide any proof, it will be done.
