Usually they have method to cheat which is why they are caught and associated to an account that previously do the same strategy that result to ban.
Cheaters would need to be smart enough to find someone willing to lend their account who isn’t active in gambling. Otherwise, if the person is, they might sell the account to multiple gamblers, and that’s where things get messy, imagine different people using the same identity. Total chaos. Honestly, I hadn’t thought about that kind of risk, lol. But now it’s clear how risky it is to gamble without using your real identity. If the account gets banned, it’s game over, and worse, your funds are frozen. That’s a real gut punch, especially if you’ve got a significant balance stuck in there.
By the way, this is prohibited by the rules and if this is detected, the account will simply be blocked. And if we talk about selling an account, then most likely such an account should have a KУC, and I don’t know who could agree to sell an account with their data. I suspect that there are such people, but they simply do not understand all the responsibility that can follow. But perhaps if they are not interested in continuing to play in the future, then they will not care.
Although the casino can detected that, those gamblers will not stop for trying to do the same thing. Maybe they will try in the other casinos that they don't use before so they think that they will have the chance to pass the blocked.
But the casino smarter than we think because casino have a team that can check and identify those abuse that happen in their place. If they found their members sell their account to other people, they will not tolerate it and will ban the connection from that people.
It is never ending story between the casino and the gamblers so it will still continue. We don't have to be like them and it is better we use gambling for fun only.
