The problem between BB and the average prostitute is that her choices are not a job she keeps separate from other parts of her life, she revels in degradation, she revels in abusing women and she defends people like Andrew Tate, her entire persona is that of sexual degradation, loathing women and pandering to the most repulsive of men. There's no chance at all that any child would be shielded from that.
Nobody normal would want to spend even a minute in her presence or company, her parents are happy to cash in on her degradation, and the only normal influences the child would receive would be at school, where they would be mostly ostracised because of their mother.
She might not traffick the child (but then again she has no moral compass so she might) but the child will be groomed every single day just by living with her, and will be in the company and presence of predatory men as their daily norm.
It's horrifying outcome for any child, and even if someone rescues the child they will then have to know that their mother is this awful person.
I hope it's all a lie, I hope she's sterile, and I hope she never attempts to have any influence or input on the life of any child.
