According to women I know, they get inappropriate nudes and requested of them infrequently but it’s not a total absence either. It’s been a meme, too. As this thing mimics human text its going to happen without intervention.
I mean, yeah, it's not great even for a regular non-child-mode. But then that has nothing to do with anyone's age, it's just 'send me nudes' isn't a good continuation of the conversation.
