Infamous User on fanon wiki, Real Name: Tanner Schnabel
Tanner, at 1st thought to have sockpuppets, later was found out to not Be The sockpuppet guy, but Another Guy named Ben.
Later, a Skype conversation revealed
Tanner to be a made up person. Sarah is actualy Tanner. It was revealed later by a crat at SBFW that Tanner was wanting to be a girl, but he is actaully a guy, thus "Sarah" might have been made up.
It remains unknown what compelled Sarah to go to such lengths. However, it is spectulated that she made Tanner up in an effort to troll Ponyo Fan.
