Just something I've noticed in my area.
I had a BJJ instructor who was a purple belt at the time (now brown) and 3rd dan BB in traditional Jiu jitsu. When he was teaching the BJJ classes he would wear his black belt?! I find this very misleading. I've noticed this on other club websites (blue belt in BJJ and BB in JJJ but when teaching BJJ they wear there black blets).
Anyone notice this happening too? Thoughts?
