My argument in favour of Mozu not counting as a sex worker is very simple; she's never opened a fansly or any equivalent to it, nor does she make money creating pornographic content. Has she made fetish content before? Yes. Briefly, which she later decided to remove. I would prefer if she never had done it in the first place, and if she ever decides to go back to it, I'll drop her like a spitting cobra. But the fact remains she chose to stop making it, even when it was the most successful material she'd ever made. That takes a lot of effort and a lot of backbone. It's not easy to say 'no' to free money, especially when so many other vtubers see nothing wrong with it even as just a 'side hustle', like Filian.
