I agree with you on that,  many gamblers tend to take things too far and how we can well be guided at some point, having a win and win doesn't mean it a right to keep winning on the games no matter how you have played and become skilled in those games, since gambling outcome is not a predictable thing so it become almost impossible to tell which game will end up as winning and which game will become recorded loses for some also, for that, anyone that is looking for a steady winning may be doing so at his own risk since he will end up being frustrated out because of his inability to have his perceived desire results.
But if anyone feels that a casino has rigged the game, the best way to handle such is by bringing up evidence to support the claim and also building enough concrete evidence that will support such claims, That far so good, but stake still seems to be the best and most widely used casino that we have around.
