Even though you didn't provide any evidence at least your question has now been answered, are you relieved?
Cheating in any casino is prohibited and it is not recommended to continue to do this for profit.
Every casino must take firm action against cases like this because it is not only detrimental to the casino but also to the detriment of other gamblers who have to work hard to get bonuses from the casino.
I don't know why they did something like that, even though playing in the right game can provide more benefits than wasting time cheating the casino by only expecting a bonus.
