Shrink,
I have agreed with you on almost everything and respect your opinion but this "statement" thing is not a great idea - and I say this with YOUR interests in mind.
By taking a statement, you are legitimizing a book. If that is the case, if a book goes down, is the RX going to cover for them? After all, since the RX told the players that the book was fine, and the players trusted the RX who should be held responsible for that breach of trust?
By psuedo-auditing, you are practically putting your stamp of approval on it. If that is the case, when/if a book folds, is the RX now going to be held responsible? I don't think you would want to get into that.
Banks have a similar system of validation and ground rules for FDIC - but that accreditation that a bank has is more of a group "insurance" where a deposit up to $100,000 is insured. The banks pay money to be a part of the system and get a TRADEMARK as a result - meaning it can call itself "FDIC insured".
Now, can we have "RX insured"? Is that a possibility? Would books be willing to pump in $X apiece to be "RX insured" and use that as a trademark? If any book folded, the RX INSURED company would take care of any player up to $5,000, maybe? Ultimately, players would ONLY deposit money into books that were actually "RX insured" and the other books would have to either join and follow the rules or try to scam their way to a profit. It would also help books in that there would be less of a chance of a run on the book because of a stupid rumor - and we all know how that spreads.
Anyways, that is just food for thought Shrink - but I wouldn't get into this mess without a LOT of financial backing from some of the top sportsbooks out there and even if I were to do it, it would be more for an "FDIC insured" type of thing than anything else - and if you actually could pull off an "RX insured" kind of trademark, it would be truly revolutionary.
