That's just plain old not true. Stable Diffusion absolutely can generate a likeness of a celebrity, just try it here[1] (I just punched in "Uma Thurman" completely at random and got a few likenesses of her face returned to me). You can download the public model and tweak it to go even further[2], eg nude.

>Additionally, images or video of another person posted for the specific purpose of faking explicit content or soliciting “lookalike” pornography (e.g. “deepfakes” or "bubble porn") is also against the Rule.
So, any lookalike pornography of any kind is against the rules. "Deepfake" is just listed as an example. The method used to generate the lookalike pornography is irrelevant - Photoshop, GIMP, hand-drawing, Stable Diffusion, deepfakes, whatever - it doesn't matter, because the result is still "lookalike pornography", which itself is against the rules. There's more verbiage on that page that continues to make their stance clear:
>Intimate media include a depiction of the person in a state of nudity or engaged in any act of sexual conduct, including depictions that may have been faked.
Regardless. Say "any lookalike pornography of any kind is against the rules", then surely content fitting that rule, would be removed from the site. But if people keep submitting such content to lets say r/nsfw, then the entire subreddit won't be banned, only the content removed (by either moderators or administrators).
Instead, (hypothetically) what's happening, is that reddit is removing entire subreddits containing pornography because some of them contain look-alike pornography. You see the conflict now?
This is just plain not true. They very clearly ban AI-generated NSFW content, hence the removal of the subs:
>Additionally, images or video of another person posted for the specific purpose of faking explicit content or soliciting “lookalike” pornography (e.g. “deepfakes” or "bubble porn") is also against the Rule.
I Google'd "reddit rules", this[1] page was the top result, and under "Rule 3" the reader is linked to this[2] page, with the above quote.
