All casinos will have unhappy costumers that will scream scam but all issues need to be investigated also. Haven't followed really in detail the ongoing accusations but all cases need to have proof and hopefully it all gets resolved quickly.
Don't forget that there are people who want to blackmail betting websites knowing that the forum have a habit of being hard against betting sites. Several times after having long discussions it turns out the accusers were manipulating to take advantage of the sympathy the community shows. So unless an accusation have enough proof, it's completely waste of time for everyone and harassment for casinos too.
I agree with you, at every point in time, casinos are sure to have one to two or even more unhappy customers accusing them of being a scam or something similar.
I am just coming from owl.games ann thread and surprisenly, this same accusation is on there as at the time of me typing this reply, many gamblers clearly do not read the rules and terms of service of a casino before depositing money and playing there, they just go ahead and do what ever they like and device all means to win, not caring or wanting to know whether the casino supports such devices or frown at it, they just don't care..
When they are eventually caught which most times, the casino keeps quiet until they win big amount and request a withdrawal, and then the casino takes appropriate action on them..
They come out to scream that the casino is scam, sometimes without proper evidence, and some other times, they hide the evidences that would implicate them, just to gain sympathy from the community.
