Seriously.  At the most, the article should note that "several large Smash Bros. tournaments have been held.." but it shouldn't provide this many specifics.  These people don't need a mention because their names in this article exist basically as advertising rather than as relevant, informative content.  Would a printed encyclopedia article about Smash Bros include such specific information about those who hold tournaments?  No, but it would likely acknowledge that such tournaments exist.  Don't worry, I'll fix it up sometime soon.
