I don't know much about AI and all that, but is there really any chance of that happening? each person that clicks on the AI gets a basic template and then, each session you can reset the AI so it doesn't really do anything out of character unless you take the time to train it too, and having an adult switch would pretty much eliminate that no?
and anyone who is using the adult switch I doubt would complain about anything an AI says, because well, they're most likely saying some pretty weird stuff to the AI and would be pretty embarrassed to have it monitored or moderated.
for me the nsfw hasn't been a problem because I most enjoy teaching it to sit on my face, smother me, suffocate me, tie me up, slap me around and all of that wholesome sfw stuff
the issue I have had is its memory, it feels so...random I could have chats where it seems to remember for quite awhile and then other time it completely forgets after a few sentences
