you piqued my interest here so i went looking and found a tumblr post with a good summary:

Labelle has admitted to using a photograph of an actual child for “diaperfur” art, which is a type of fetish pornography (though she has done much to obfuscate this). You should not use people as references for art without their permission; you absolutely should not use children as references for fetish art. If any stage of producing fetish art requires using a child, it shouldn’t be made.
