It's mostly people who do not follow the rules and when the casino takes away their money (and most of the time that money is frozen, not spent by the casino) because the user broke the rules, that means that the user will come back here and start to complain here, even some people who did not have a user account here and opens a newbie one just to complain about it only to find out later on that they were the ones who broke the rules.
Rules are clear and bold enough and those users just try to break rules intentionally because they think they are smart enough to outsmart the casino. What do they have at the end?
They only can complain without proof to show that they are innocent and victim. In contrast, the casino has full set of data for user law-breaking activities and when they pull the serious card like account termination, it's serious enough because they don't easily self-harm their reputation. I've seen many cases like this, complain day by day, use bad words and eventually when results are out from customer support, more violations are detected.
This is 100% true, and that should be the most important part of the situation and shouldn't really have anything that would be crazy in result. I get that we are not going to end up with a situation that would be fine or something like that, but it should end up with something that would make sense on the long run.
I get that it's not easy to catch all of them, so some people do end up with a result that hurts a bit, but that doesn't mean that we are going to end up with a zero caught rate neither, some of them will be caught after a while and they will keep on complaining. Anyone would know that complaint is actually blackmail, as in "I will keep on complaining everywhere until you pay me" and glad that casinos do not get baited.
