if, and only if, you have a hard evidence that he is bogus, then i think people can sue him.  take it to judge judy.  she'll knock this one out of the park within 30 minutes including the commercials. 

I agree with Iceman. The school I go to has a black belt board that keeps harmony among the sister schools and you have to apply to get permission to open a school under the Jung's name. 

Sadly anyone can open a school and call themselves a "grand master" and have a certificate and look nice with being able to order uniforms and black belts online.  Most people don't know to look at schools affilations and check stuff online first. 

I just want to clarify to all that it is NOT my master that I am talking about.

This guy is the owner of a school where they teach mixed martial arts for cage fighting and such. It just so happens that there is a 16 page forum posting about the various fraud schemes this man has pursued and I know who he is.  I know he claims to be a master but he has no accredidation that I have seen.

I just wondered what your thoughts were on the question of if I should mind my own business or not.

It sometimes hard to take down a person that has such a large following. However, it can be done.  The best thing to do is not act in retaliation and with emotion.   Remember my student; The pin is just as mighty as the sword. The same can be made about the keyboards in our time.  Take your time and sit back and watch. The ancient texts speak of what ever is done in the dark shall be brought into the light.

A real martial arts Master has been groomed from his/her grandmaster to be a great leader. You can tell a leader from follower. You can tell by watching them train and teach. Look how other masters Act and take note. Use the internet to see what other masters or doing all over the world. Take note in how he or she moves and interact with others in the world around them. 

Different masters act different ways.  Look at the certification that they claim or have.  If possible talk to other masters around the city that the master is around. Be very careful in people that make the own styles with out Traditional advancements in other Traditional styles. Look at the age of the master a master has to be at least 30 years old or close to it by a few years. Sometimes like in my case, I was awarded my rank earlier because of my championships and former military service and advance trading over seas.     A master has to be at least 5^th Dan over seas or 4^th Dan in USA.  Ask who is the Masters Grandmaster?  Who did the grand master he trains from? All masters will gladly/proudly  tell you there lineage.  

Some masters have a large certificate that Says master. Others do not they certificate displayed openly.  Check the internet WTF or Kukkiwon registered black belts have there information open to the public   http://www.kukkiwon.or.kr/english/index.jsp  . At the bottom they will have check  poom or dan. You will need the master’s birthday and full name that was submitted to the kukkiwon.  

Most Masters modern masters blind in with the public. Most masters don’t drink or smoke.  The are fit or if not can move as if they or fit.  They all are able to move faster. Or slow but with the end result victory.  They have good gross and fine motor skills. They easily beat black belts. They are kind and relaxed.  Most of all they don’t use martial skill in danger but metal skill. Most masters or spiritual. They do mediate.   Most Masters are always learning and striving to improve themselves and people around them. 

Masters make black belts.  They should have black belts they have promoted.  Masters hang around other masters. Why cause its get lonely sometimes. And it Is the bomb to beat up on your students and far too easy. It’s better to have a master you can train with and can aid in bettering there skills. Master have other great people following them. Men, older sometimes younger that train or learn form him/her.  Masters have taught. To be a master you have had to have demonstrated how to learn and how to teach and teach others to do the same. 

Masters are charged with helping others spiritually mentality and physically.  They always want to help others as well as protect others.  Masters or mentors.  I can call my master and grandmaster any time day or night with important problem. Most masters have common sense and wisdom and the ability to be political.

A good master thinks of his/her school and strives to be honor to their country and is a over all roll model.

Also id likes to add that masters are very of wise of the human body. So wise they have physician like qualities.
