See the MT Rules, at 1.10.3, and 4.16.1 and 4.16.2 (pasted below for your convenience):
1.10.3 No Individual Bashing / Fraud Busting.
It is not our mission to out and expose frauds or decide who "sucks". Such discussions rarely lead anywhere other than to headaches, and lawsuits.
and
4.16.1 Fraud Busting
Due to its nature, this forum encourages the asking and answering of questions. Many times one member will have questions and concerns about the history, skills, lineage, or paperwork of another member. In other cases, things may be stated on a webpage, flyer or article relating to a member that raises some questions. Sometimes, comments will have been made elsewhere and those issues carried over to MartialTalk.
MartialTalk and its staff encourage the polite and professional search for knowledge. Questions and concerns may be brought up, with the understanding that the other party is under no requirement to answer.
Most questions may be raised within the forums dedicated to a particular art or area of interest. For example, Kenpo Lineage questions in the Kenpo forum, are fine. Others of a more serious note, are to be limited to the “The Great Debate” forum.
Excessive “Inquisitor-style" questioning is not allowed and will be subject to administrative action. If you have had to ask a question more than 3 times, you are most likely running the risk of “excessive’.
In addition, “Hot Pursuit” actions will not be tolerated. The “Hot Pursuit” is defined as asking the same or similar questions in multiple threads and / or forums.
Members who become ‘obsessed”, ‘inquisitors’ or ‘interrogators’ will be subject to administrative action. Members who are involved in excessive arguments that disrupt the forum, may be subject to administrative action due to the disruption of the normal operation of this forum
4.16.2 Credential Verification
The staff of this forum is certainly concerned with the rising problem of falsified and otherwise questionable credentials. Due to the costs in time and money, as well as possible language barriers, we are unable to perform verifications. Because of the number of different organizations, splits and other divergences, absolute certainty of authenticity can only be achieved in a few select areas.
While each member of our unpaid, volunteer staff has their own area of knowledge, we do not feel we are qualified to evaluate the skills of those who have not trained in our own arts. The “Karateka” is simply not qualified to decide if the “Kenpoists” ‘Karate’ is any good. Each art has its own requirements and guidelines. It is humanly impossible to understand them all.
The simple truth is this: there are thousands of opinions on what is right, and wrong in the arts. We encourage our members to share their ideas in a polite manner.
MartialTalk staff will not be involved in ‘credential’ verification or ‘skills evaluations’.
