from another forum:
He is a guy who boycotts the IBJJF because he claims they wouldn't accept his rank as being legitimate unless he pays $2,000.
The story goes (as best as I remember), he was a good grappler at brown belt (I don't remember who he trained under to receive that belt, but nonetheless) running his own school and helping out at another school in the area while taking some classes there but not really being a full student. That school approached him about running classes regularly and would in turn promote him to blackbelt. He accepted this deal, but before it could all go through, a cost of $2,000 came up from the IBJJF.
The blackbelt at this other school him was going to become an employee of was not a second degree blackbelt and therefore couldn't legitimately rank him without the documented approval of an IBJJF registered second degree blackbelt (of which there are in the association he belongs to). As the local blackbelt brought up the promotion to a higher up, it came down that $2,000 would need to be paid to the IBJJF for the promotion to be legitimate. This is unusual, because the association he would've been ranked under was already registered with the IBJJF. The only way I can think the $2,000 would come in is if him intended to run his own academy independently (the cost of registering an association with the IBJJF). But I don't KNOW that - it's just what I can reason based on my knowledge.
Long story short: he was verbally told he'd be getting his blackbelt, but since the promotion fell through due to money issues, he was never awarded it. He decided to put on a blackbelt anyway because he was told that he'd be receiving it, even though the promotion never physically occurred via documentation or any kind of ceremony. His skills as a grappler are not in question, but his insistence on wearing a blackbelt that he was told he'd be receiving yet never actually did, is what rubs the community the wrong way. He should've joined another school in his area under a second degree blackbelt and took the extra time to be officially ranked, regardless of him deserving it sooner or not.
