BitterGrey is a pseudonym used by the editor of one of the oldest websites on paraphilic infantilism. Originally known as BitterGrey's Den, Understanding.Infantilism.Org opened in 1995.
In 2006, he became involved in Wikipedia, donating text from a then newly developed article, "An AB/DL Primer" and later, some references found while updating the article "What is Infantilism?" to help rebuild the recently stubbed paraphilic infantilism article. Even five years later, most references in the Wikipedia article on paraphilic infantilism were from that source.
The same is also true of the diaper fetishism article, which borrowed text and references from the paraphilic infantilism article.
Given this connection, it isn't surprising that some editors with disagreements against BitterGrey from unrelated areas of Wikipedia end up deleting material from the paraphilic infantilism and related articles. Discouragingly, this set is not limited to vandals and novices, but includes users with moderately high edit counts, professionals, and administrators. What these editors might not consider is that in effect, BitterGrey's contributions to paraphilic infantilism and other Wikipedia articles were good-faith donations to a competitor. By disrupting, vandalizing, etc., these editors are actually improving understanding.infantilism.org's competitive position. They are only hurting Wikipedia.
