Hezzer/czmkujm6s7 will still always be one of my all-time favorite. Worked in Daz3d, made amazing pictures of shotas getting emasculated and femmed, sometimes by women, sometimes by futa. Really bloody, which I love, and the poses and camera work were top notch.
They were on Pixiv as Hezzer for a while, and they were fairly popular, but they either deleted all their stuff, or it got deleted by someone else. They were active on fanbox as czmkujm6s7 for a little bit, but that's gone now, too. A decent amount of their stuff was archived for a while, but now all I can find are their (relatively) safe works.
