Honestly, if you use search engines, they will give different results over time. For example, Yandex gave the first answer from drhouse99 https://bitcointalk.org/index.php?topic=5496834.0, but a Google search gives the answer from Furtikzergagil. https://bitcointalk.org/index.php?topic=5446294.0
But in my opinion, your assumption is very reasonable and serves as even more evidence that the OP was not entirely honest. I often see casinos accused of not paying out winnings, but in most cases, this is due to the user's fault. The entire casino security system is triggered when searching for duplicates, and they can allow users to play for a long time, but when it comes to withdrawals, questions will always arise. Casinos should not give away all their detection methods; otherwise, they open loopholes for cheating.
