PSA / COMMUNITY WARNING.
Matthias (tumblr user houndpack, asmodeus-psd, hcunds, asmvdeus) is a "dead dove friendly" content creator, tumblr roleplayer and ao3 user who writes smut about characters as young as 15 and most recently toddlers, focusing on graphic depictions of their underdeveloped bodies. He tries to pass it off as age play and spreads misinformation about the kink community in an attempt to excuse this dangerous behavior. He'll even argue, in his own words, that "fictional people (words on paper, pixels on a screen, etc) cannot be harmed beyond their fictional world".
This is just him talking down to people, but it's not about hurting fictional characters, it's about hurting real people by normalizing the sexualization of children through fiction. That's why this content is not allowed on Tumblr or most of the rest of the internet, even in text form.
