I think there is a common misconception in this field. There are mostly nsfw male-oriented bots because the majority wants exactly that, from a creator and user standpoint it's just normal to see this outcome. The ai bot scene I dominate by horny guys. (I am one too 😅). So it will never really change at that point. Myshell could say that they limit nsfw and sfw bots to the same number, but that's like a creativity restriction and would feel like censorship. The only thing people can do is make their own bots to try balancing it out, or at least having their own taste satisfied. I enjoy male- and female-oriented nsfw bots as I am bisexual, also sometimes good story sfw bots are nice too.
So in conclusion, it's not up to Myshell to satisfy the user it's the responsibility of the creator. And the user base tells what will be more profitable and what not.
This all might sound a bit hard, but that's how it is.
