Ah, Wikipe-tan is so cute!
Wikipe-tan
A fictional anime-style preteen girl who is the official mascot of Wikipedia. Originally created by Kasuga, an admin on the Japanese Wikipedia. After it was learned that Kasuga draws cartoon child pornography off-site as a "hobby", this caused a minor PR disaster on Wikipedia. (Ironically in Japanese, "tan" refers to someone you want to have sex with - in the case of Wikipedos, a preteen girl apparently).
Wikipedia administrator: "Oh no! If the public finds out that the creator of Wikipe-tan is a hentai child porn freak, this will destroy Wikipedia's reputation!"
