Why do casinos limit or ban a user when he or she is winning too much, but do not do the same when the user is losing too much as well?
I have not heard of some casino banning because the user kept winning. But maybe they suspect the user has found a glitch in the system that made him win over and over. If the user is draining the casino's funds, I think that casino already has a capital problem which is something that users will also need to avoid.
