Exploiting rule loopholes in obscure Chinese kickboxing events doesn't constitute much of a "WIN", especially with his subsequent presentation of himself as a "world champion" and "experienced mixed martial artist".

All up, a call for "concrete examples" is exactly what should be going on. From Tim. Not from the unbeliever. The cliche is "the onus of proof is on the believer". Tim's extraordinary claims about drug-free muscle gain, for example, should have had a third-party drug test involved as well as being put in context with his previous and subsequent physique. His extraordinary claims to be a martial arts champion should come with names, dates and number of competitors in his division. Etc.
