Thank you for taking the time to review the profile. I want to clarify that all black belts under Piet are fully backed by Renato Tavares, who has always ensured the legitimacy of each promotion. I’m confident there’s no reason to doubt the authenticity of any of these belts. I believe there’s no need to ‘split hairs’ over a lineage that is well-documented and supported by respected figures in the jiu-jitsu community. I’m open to any constructive discussion about this, but I hope we can focus on what truly matters: the growth of the art and mutual respect. Best regards.”
