OK, so, sometime last week, a friend of mine got so lucky with his sports betting that he kept winning all his bets, he said himself that he wasnt even sure of some of the games he bets on but he somehow still won it, and according to him, after winning ten times in a row consecutively, the casino placed a limit on the amount of money he can bet in a game, he said he was betting around $500 or more each time, but after being limited, he can't bet more than $10, he got agree and decided to open another account on the same casino (his first mistake), then withdrew all the money on the first account, and deposited exactly the same amount on his second newly created account (his second mistake), and then placed his first bet, and when he came back to check, he discovered that both accounts has been banned, it turned out that immediately his bet on the second account won, the account was banned together with the first one, he's been talking with the casino customer care to atleast allow him withdraw his money, but they said they won't allow him access to the money until after 365 days, that this is a punishment for what he did, and because they don't want to forfiet his money, he must wait, and come back after one year to withdraw his money.

Now, I just want to ask us, if you own a casino, and a particularly customer is always winning, winning and winning, would you kick/ban the customer, or limit him or her?
And why please?

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?
