I totally agree with you.
Some guys think they can outsmart the casino, and when it doesn't work out, they come to the forum crying foul. The truth is, every casino limits this type of betting behavior. If you're caught doing it, don't expect them to give the money back ,if casinos started refunding these kinds of accounts, it would just encourage more of the same behavior, and the cost would be massive for them.  i am a prefessional sport bettor,i will take my own risk, i will cash out before they find out, there are some kind of technique and tool can be used, but i assume they never find out.
