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?
Sure but then on the other hand, gore is banned, and that can exist in artistic nsfw forms too.
It's not everything or nothing. Or if it is, then I'd rather have everything.
I don't have anything against any kinks, I just think there are levels to it and scat is beyond the line of comfort of most people. There are loooots of categories that probably wouldn't even make it to lemmynsfw so it's not like I'm singling out just this.
That doesn't make it bad, it's just something I suggest showing only to people who actively look for it. And Lemmy doesn't have such tools at the moment.
