I believe that "Kohayashi Hayashiko" may actually be "Kobayashi Chisato". Googling the former would bring you http://netcity3.web.hinet.net/userdata/nakobaka/, the webmaster of which shares the birthday, name and e-mail with http://nakobaka.myweb.hinet.net/, an URL that comes up in earlier images and would eventually move to http://www.pockyfactory.com/
Not to mention they're all linked by the site name "Pocky Factory"
