As I mentioned to you in your casino, I'm reasonably sure that these would fail US UIEGA provisions of the US Safe Port Act and would thus be subject to removal by LL along with punitive actions against the casino owner.
The bit that people have historically had difficulty understanding about the UIEGA as it applies to gaming in
SL, is that the element of chance is what puts gaming afoul of the law. There have been numerous attempts to get around this by substituting intermediaries between L$ and US$ but that loophole was never there to begin with.
As I also told you, I don't AR anything. But I wouldn't be too surprised if you find your account locked "pending investigation of gaming rule violations". There are a fair number of unhappy former-casino owners out there who may well wish to "share" their unhappiness.
