It's laughable. Because your account has been flagged doesn't actually mean that the casino/service is actually a "scam". What it actually means is the casino is doing their job of making sure that there are no nefarious entities doing nefarious things in and through the casino.
Plus the number of the same complaints in other casinos could probably also mean that they could be used as a mixer/tumbler too, to obfuscate outputs.
I'm NOT accusing you, but if your account is flagged, then you might need to wait until it's verified as a false-positive.
If an account is flagged, it is not the end, and there is available chance for dispute. From flag to officially closing an account, there is other steps to do from the casino and matter is whether the casino does their action against an user account with enough solid evidence of abuse on their platform, violations of their Terms of Service.
If they take severe action to close an account, with valid evidence, any accusation that says the casino is scam, is truly invalid.
