I don't have issue with NSFW content per se, but this? This isn't a problem of whether NSFW content should exist. It's a much bigger issue than that.

First, mental health issues surrounding this are far from being solved. Having a sycophantic robot faking intimacy looks manipulative, ripe for exploitation, and damaging to long term psychological well-being.

Second, this is a service that manufactures compromising chat logs and stores them for profit. Yeah, what could possibly go wrong?
