The problem might be that what we are being told doesn't tally with the length of time taken.
Players have been told that all that stands between them and payment is receiving a contact from these private investigators to confirm they are legitimate.
Obviously, they have given their full details to the casino, so it's a case of the private investigators going to the address and making contact, confirming that the person at the registered address is a player there, rather than a hapless victim of a stolen identity. Well, this is the process as has been revealed. Surely, once an address is known, it shouldn't take so long to arrange a visit. The preliminaries should be even easier, as many things like credit reference checks can be done over secure internet connections. When I have applied for things like credit cards, these standard checks have been done whilst I "hold the line".
3 months and more is simply too long for the above simple process, assuming that an EFFICIENT team of private investigators has been engaged. Perhaps Rushmore could publicise a few more figures so that affected players can understand why it is taking so long simply to arrange a verification visit to their address. There have been so few complaints about this that it would seem only a relatively small number of players are affected, even though they are generating quite a bit of "noise".
There must be other casinos hit by the same fraud, but there does not seem to be an issue of them taking months to pay their legitimate players. Have Rushmore asserted that this is some kind of unique fraud model that has not ocurred before, and is particularly difficult to resolve.
From the webcast, I have gathered that this fraud was based around hotels and photocopies of passports. This is not unique, and the scam that hit Rushmore will most likely be tried again elsewhere with the information that has already escaped into the black market. It may already be happening, and going largely undetected because casinos do not yet know what to look for.
