Wikipedia:Articles for deletion/Yama Umi Do
I don't believe this is a hoax: Googling (sensei "mark wagner" martial) brings up several websites that mention this, often with the variant spelling "Yami Umi Do", which is mentioned in the article.  However, it seems to fall well short of : the sources that I've found are mostly subpages of the http://www.goldendragondojo.com/ Golden Dragon Dojo website, e.g. http://www.goldendragondojo.com/TsunamiTruth.html "Tsunami Truth", or subpages of http://www.icmaua.com/ ICMAUA, e.g. http://www.icmaua.com/EncyclMasters/ArtistsEncyclopediaC.htm this one (do a string search for "wagner" to find references).  Neither of these qualifies as a reliable independent source; note that the main ICMAUA page states that members of the organizations can "publish your MA martial arts? bio in 'Who is Who'...", with no suggestion of peer review.  A Google search for ("imperial karate handbook" wagner) turns up exactly one hit: this WP article.  There's a fairly clear notability failure here
