Here's an excerpt from a post by blackbeltinfu made on 09/30/05 08:11 AM:
"Also Grand Master Monser met with Rob and, as he was familiar with his background including his instructor Sakata (who many claimed did not exist) invited both Rob and Rat Pack to become one of the first PA schools to belong to his new BJJ association."
Grand Master Francisco Mansor is a BJJ red belt like Helio Gracie. Rob is Robson Pereira, who supposedly was awarded his BJJ BB by the mysterious Maurice Sakata, whom no one has heard of and who may not even exist. blackbeltinfu is owner of Rat Pack Fighting Systems where Robson is BJJ instructor. So blackbeltinfu is saying that Mansor was familiar with Robson's teacher Sakata, thereby proving Robson's claims of having been awarded a BJJ BB by Sakata.
Here's the thread:

Well, I sure as hell didn't want to take blackbeltinfu's word about what Mansor supposedly said, because he earlier lied about Robson being one of Rickson's BBs, so he might be lying about the Mansor business, too. So I called Grand Master Mansor myself to ask about Sakata--and I recorded our conversation. Stand by for posted transcript...
[Edited to note that Robson Pereira is no longer associated with Rat Pack Fighting Systems.]
