BitterGrey
BitterGrey has a seemingly-lifelong interest in diapers and being a baby. With a serendipitous typo, he stumbled upon the alt.sex.fetish.diapers newsgroup and then the broader ABDL community.
With the founding of Understanding Infantilism.org in 1995, BitterGrey sought to develop and distribute information on infantilism, diaper fetishism, and the ABDL community. Initially, the focus was on gathering and presenting available information. Starting in 2006 with the ABDL survey series, the focus shifted towards original research. Since 2010, these efforts have included supporting academic research, with the goal of spreading an understanding of infantilism in mental health community.
