When the casino take action against them, they start to blame the casino on social media and here on this forum. No matter how much they plan, they can't bypass the casino security system that will detect multiple accounts or VPNs etc.
The casino never reveals the criteria it uses to detect multiple accounts. Some people think changing the internet connection or using a VPN will make them undetectable. A casino can use different ways to detect multiple accounts. It could be wallet reuse, IP address, same device, or even the same browser. There might be other ways that they use to detect multiple accounts, and the gambler do not have any idea about it.
When people think they will be able to dodge the casino, they are fooling themself. They will eventually get caught and later blame the casino. All we can say is sorry to them for getting their account banned.
Casinos are filled with people who are very knowledgeable about the system, so if we think we can cheat them, it's a big mistake because they're definitely much smarter. They have security systems in place to help them enforce existing rules, so it's best to avoid even thinking about cheating the casino.
That's a last resort for cheaters: they'll come to forums and claim the casino cheated them. And their mistake is that they don't realize that many users of the casinos they're referring to also share their experiences. So, usually, before their representatives appear on these forums, many people will have already asked them questions.
