Wada and the recent SquareEnix have become a joke among hardcore gamers in Japan. If you spent anytime reading Japanese boards or blogs you'd be able to figure that out. They are the EA of Japan.
That was one heck of an "attack." I'm tempted to report this as spam. It's just another pathetic blog stirring things up and getting hits.
Submitter here. Note that I would've embedded the video but Nico video doesn't allow embedded videos unless using certain Japanese blogs. You can't watch directly off Nico video either without an account. Also, using a translater like gtranslate or babelfish on the Japanese link causes the link's embedded video to disappear for some reason. So that's why you have to click on a JP link to watch.
