Maybe I'm a different kind of person/Jew but when did Judaism become Voodoo that Brachos from Mekubalim/Rebbeim guarantee the success of a business deal. I'm not just referring to this scam but even to a legitimate business venture. Sure, I think a Bracha can help, though we never really know. But to imply any kind of guarantee or even to take the bracha into account at all when making a business decision is absurd.
