Reddit bans users posting NSFW cyber-porn made with AI image generator

It's perfectly logical. If a person does not exist... then they can't consent to having sexy pictures of them published!
So the analogy would be accusing a student of plagiarism for using the same words (or maybe same letters) as other people (not anyone specific, but the university library as a whole).
It does relatively better at generating faces in portraits, but the more zoomed out you get, the worse the faces become. And that's just in general, not specifically nudes.
That said, as long as (a) these subreddits moderate the content to remove generations depicting real people, and (b) the subreddits are marked as NSFW with the usual "I am 18+" acknowledgement to enter, I don't see why the subreddits need to be shut down entirely.
Reddit has long stopped caring about being reasonable when it comes to subreddit bans. Their policy now is to just stay well on the safe side with things like this.
I've been privy to some of the model iterations Midjourney has gone through on their Discord and in a series of a few weeks, they've made substantial gains on generating faces from their V1, V2 and V3 models.
Within a short amount of time, this will no longer be a complaint.
In relation to OP's post, I guess Reddit can't guarantee this won't also turn into DeepFake territory so they're banning it outright.
That said... it would be lying to claim Stable Diffusion's current generations aren't nightmare fuel :D
However, Reddit isn't exactly good at making product decisions anymore (see: New Reddit), so I suppose their lack of sense isn't exactly shocking.
