A photo of the Vampbuyer incident was advertised as for sale in Taboo! Auctions
Taboo! is a popular web portal in the Science Adventure Series, the equivalent of Yahoo! Japan in the real world, offering a variety of services from news to auctions to email to web hosting.
Taboo! Auctions is the equivalent of Yahoo! Auctions in the real world; since Yahoo! Auctions is the most popular auction website in Japan in the real world, not eBay, Taboo! Auctions is similarly the most popular auction website in Japan in the Science Adventure Series.
Taboo! News and Taboo! Auctions are both found within the plot of ChäoS;HEAd. Takumi Nishijou uses Taboo! News to find out about the New Generation Madness serial killings.
Also, Taku finds out about the fourth New Gen incident, Vampbuyer, from a Taboo! Auctions link that Grimm sends him online, where a photo of the Vampire House killing is for sale online. Taboo! quickly takes down the auction page for the photo of this gruesome murder, where a man was drained of all of his blood and turned green, and the words “Whose eyes are those eyes?” were written in blood on the wall.
