You know, even well-known popular casinos sometimes refuse to pay the winners (not all of them obviously). At least you can see online reviews here and there claiming they didn't pay this and that. I know, sometimes these are false accusations, but still, certain negative reviews can be verified and are credible.
With the casinos not wanting to pay their winnings directly, the casinos are risking the casino business they have started from the bottom so that it can become the most popular casino and that will be very detrimental.
It's possible that there are indeed some people who make threads of false accusations that their winnings are not paid, but they cannot provide clear evidence about this so that we can sort it out and think clearly whether the casino they are accusing really doesn't want to pay it because I have found it myself. thread of accusation however which makes thread unable to show any evidence and disappears.
