Deletion of Satō Tadanobu

Comment: Took me seventeen seconds (I timed it) to locate http://books.google.co.uk/books?id=bzRen1dcdTwC&pg=PT778&dq=Sat%C5%8D+Tadanobu&hl=en&sa=X&ei=35t5UYv9Hc7u0gX0-IDADw&ved=0CDwQ6AEwAjgK this, http://books.google.co.uk/books?id=TqR0rij5b0QC&pg=PT11&dq=Sat%C5%8D+Tadanobu&hl=en&sa=X&ei=apt5UcSfIqbP0QW204HYCA&ved=0CDMQ6AEwAA this and http://books.google.co.uk/books?id=oGvKpxC-4kcC&pg=PT22&dq=Sat%C5%8D+Tadanobu&hl=en&sa=X&ei=apt5UcSfIqbP0QW204HYCA&ved=0CEAQ6AEwAg#v=onepage&q&f=false this, covering his impersonation of Yoshitsune at Yoshino; in fact, it took me longer to write the previous clause than it did to locate sources. It took me only a few minutes longer to find out that he's almost equally well known for his self-defense exploits with a Go (game)|Go board - indeed, the famous painting ''Sato Tadanobu Defending Himself with a Goban'' is close to notable in its own right. There's a kabuki play about him (''Yoshino Shizuka Goban Tadanobu'') and he's a major character in another (''Yoshitsune Senbon Zakura'') (which was also made into a film; ''Tadanobu The Fox''). In short, he's pretty damn notable, and I haven't even checked the ja-wiki article for additional sources yet. Given the persecution that the article's creator has received at the hands of a certain known sockpuppeteer, and the clear evidence that  was not followed, I'm having a hard time believing this to be a good faith nomination. I haven't the time to sort the article out tonight, but I'll do some expansion work on it tomorrow
