Well, tbh, I doubt many know their true gender but I think everyone assumes its a guy given Men are more commonly linked to the production of sexual works (art, games, anime etc). Thats not to say women can't produce things in this form of the erotic genre, but it's rare. As for the name, it could just be a tactic to get more support for projects. I mean, memes aside, guys are more likely to support a project if they think a woman is behind it. I don't want to label these guys with stereotypes, so you can draw your own conclusions about why they do this
