Thing is someone would have to force them to do so. The IBF was forced by the FBI I think but the WBC is based in Mexico, WBO in PR and WBA in Panama and it seems like the authorities in those countries are not in a hurry to investigate their obvious corruption.
Problem is also nobody calls for their arrest either, unless a disgruntled fighter does it at one point. The system of mutual favors and short-cuts benefits the most powerful promoters just as much as the organizations, it further ensures their leading role in the market, it’s not their interest this system to end. It only the interest of fans and less powerful fighters, promoters but anyway if a fighter would even entertain the thought to get at their neck they risk being blackballed by the industry as a retirsion for fukking with their money.
