Check out https://rentry.co/lemmy_nsfw411 for a categorization of NSFW communities

There are also, that I am aware of no communities like r/NSFW411/

The ownership of !nsfw411@lemmynsfw.com was given to me by the original owner because of my attempt at making an r/NSFW411 equivalent for lemmy.

I was hoping there would be more people giving feedback or recommending new communities to add to it. (But so far there was only one person requesting to remove a community from a category.)

Edit: I also agree with the first part of your post. If everyone involved is 18+ and it’s consensual, what’s the problem?

You can also suggest pornlemmy communities to add. This is more as a first sketch.
