If he is "a beginner" and not yet good then what is the problem with him appearing in low level bouts? Isn't this exactly what he should be doing? It would make no sense from his point of view to appear at a level that is above him. He would lose and look bad, and it wouldn't do his advertising much good. I think it is pretty obvious what he is doing, and it isn't training for serious MMA comps.
It seems as if you want to see him get beaten up or taught a lesson for some reason? He is selling wing chun FFS, I think he is probably aware that he isn't going to be the next MMA world champ.
Similarly I can't see any problem with Harman using video footage of amateur fights and sparring to promote his wing chun teaching. There is no secrecy about what the bouts are. He isn't lying about anything, beyond the obvious piss take titles of the clips which are probably intended only to wind up humourless blowhards.
He is doing exactly the same thing as Alan Orr, only in a much more risky (and some might say much less sleazy) way, since he is actually risking his own neck and the possibility of embarrassing video footage, rather than someone else's.
It makes no sense that this minute thing bothers anyone
