Is it just me or do all the AI generated porn images have something in common that makes them immediately recognizable? I am not quite sure what exactly it is but they do all have some quality in common.

There might be a need to handle the cross-community spammers on an instance or Fediverse wide level though, in particular the ones who post to any porn community with the same title and picture regardless of the picture/title being on topic for that community.

The downside of that is that a lot of OF content is posted to dozens of communities and this fact is the main spam problem with them, not necessarily the content in any particular community on its own.

Since the version number at the bottom does not include a -nsfwpatch suffix I assume that hasn't been ported to 0.18.1 yet.

You can easily look up the owner of the IP address space to get the provider.

Staying quiet is probably a habit developed during teenage maturation years (while still living with parents).

Caching has other downsides though, mostly for content that might not be legal in an instance's jurisdiction.

Actually it would still show up in All as long as at least one user on this instance is subscribed to a community on the other one. Just not in Local.

The problem is that some of the categories of images that people might not want to pop up in their feed are very vanilla, e.g. dick pics are not kinky or extreme, just not something a lot of straight guys and lesbian women want in their feed. So should they also not be posted? What about feet? Some might not want giant pictures of feet on their screen. Or maybe rough sex? Some people also really don't like cuckolding, so no pictures with captions or post titles for that? Where does it end?

Not just on the internet.

I very much doubt the concept of celebrities (at least the ones who are celebrities largely based on looks or visual performances in general) will survive the AI development to the point that is the premise of this post.

I don't think that it will ever fully take over because part of porn is selling a fantasy and that doesn't really work so well if no real people are involved in the production.
