Thanks to "The Goat" for the scoop. You'll remember there have been similar cases of vandalism-gone-wild on articles for the Liancourt Rocks, the Sea of Japan, Yi Sun-shin, and Kenkanryu. Actually, pretty much anything having to do with anything at all Asia- or Korea-related will invite vandalism and race-baiting between Asian nationalities and Hyphenated-Americans, so that's why I always disable comments on my youtube videos.
