Many players always try to outsmart these casinos, yes because I have seen it in several occasions. Initially I have alleged strongly that it is due to negligence of T&C by the clients. But on a second thought this appears to be deliberate. Deliberate acts to increase chances of winning. But since the company has stated it in their T&C, it doesn't matter again if the gambler is not aware of the rules or deliberately skipped it.
They think they can compromise a system on casino and cheat, win and withdraw successfully. It is very stupid. With cheaters, I don't think they use their own money or big own money to bet and cheat. They will try to compromise casino bonus, free spins and some sort of promotion.
It is their responsibility to read event rules, casino's terms and conditions. It is stupid to ignore important rules and come back with invalid scam accusations. Act and play according to ToS is better and save time for stupid activities that lead by greed.
