Again, I don't accept the identity excuse, because that's all it is.
As long as they don't abuse the system in place, such as through bonus scamming, why should players not be allowed to try and circumvent an identity check? Such acts are not dishonest, because they don't change the odds, and are merely a response to the casino's out-of-control greed. The thought of losing money to anyone is too unbearable. Let's not accept that sorry attitude as law.
Since a casino's identity check is not law, if somebody slips through it the only appropriate response is: "Too bad. Enough with the crocodile tears already. Pay the man his money."
