Deletion of Den Klyuev

Comment: Despite a seemingly impressive record, there are no independent sources to support any of the claims so  is not met.  I'm also concerned about the accuracy of the claims.  For example, the article claims he won a medal at the WKF world championships in 2013 but the WKF holds its world championships in even numbered years and I found no mention of a special shito-ryu division at the WKF website
