Your answer is what i thought, nothing players can do except maybe even if they close down isn't it a fact they conducted business and defrauded people? don't they hold business licenses? Aren't there actual people that own this sites? I personally would be very worried if had such a business and intentionally did so. Fraud is fraud.
I'm quite sure that most casinos whether land casinos or online casinos try til the very last possible solution to make it right by the clients that patronized them , not doing that would certainly open many doors for much bigger headaches.
Money is in fact the root of all evil........
Online casinos have vanished with players' money before, and in most cases no-one has been held personally accountable. It is a company that folds, and when it does, it folds as a "limited" entity, which means that once the company is in liquidation, players, employees, suppliers, etc all become "creditors", and the assets are sold and divided between them as so many cents in the dollar of debt owed.
There have been some notable failures of companies based in respectable jurisdictions, yet players have ended up losing thousands with no means of redress.
All players can do is hassle them repeatedly for payment to ensure it is not they who end up unpaid when the worst happens, and once paid, stay well away.
Rushmore have lived a charmed life in that they have managed to pay in the end, and then announce "issue resolved, business as usual", only to encounter the same "issue" a month later.
When they had a rep here, she more or less burned herself out trying to keep us happy, and in the end she left Rushmore and was not replaced. Management seemed to view her as an irritant.
In the past, their excuses were at least credible, as it was US players suffering the problems, and players outside the US were mostly getting paid fast. This changed recently, and now ALL players suffer "processor delays". This is the point at which the excuses began to unravel. The EU did NOT pass UIGEA, so there should be no problem getting a decent processor to do what is LEGAL in most of the EU, and at standard cost to the casino. Despite this, they seem to use the SAME dodgy US facing processor that will break the law and hide the nature of the payments so that US banks think it's payment for things like "consultancy work", or a refund from a certain bike shop in the middle east, a service for which the processor charges high fees, and with the risk to the casino that if the feds start sniffing around too closely, the processor will run with the money and hide, leaving players and casino out of pocket.
Lock casino made the same mistake. A EU player was owed a considerable sum, and upon investigation the casino admitted that "his money" had been on US soil, and had been seized by the DoJ. There was no reason for "his money" to be anywhere near the US, and should therefore never have been at risk of a DoJ seizure. This was after UIGEA, when operators knew that every cent on US soil was at risk, and that payments to non-US players should NOT be mingled with payments to US players.
It seems Rushmore repeat this mistake over and over again, and have EVERYTHING going through the US.
What they should have done is to open Euro denominated skins of their casinos, and served non-US players with these, perhaps with a flagship UK Pound casino for the Brits. Euros don't go near the US, not even briefly in transit, which is a problem with the US dollar. Club World had a UK pound and Euro version of it's flagship casino, and even though they still serve the US, their problems are nowhere near as severe as those suffered by Rushmore.
Rushmore may well have started doing this, but seem to have left it too late. Along with US players, they are in denial that this time the US government have effectively won the war, and all that is left are pockets of resistance that are being put down one by one.
