...because they are just not really surreal. You can make the collection "images that have somehow to do with surreality" and put these images in that collection.
Furthermore, I will delete any sexist or disgusting collage from this collection, because surreality has always to do with a certain dignity. E.g., Magritte never made any disgusting artwork, even if he was allowed to do so.
I might also delete members if they continue to put their artworks in this collection randomly, just to spread them over toonpool.

sounds reasonable

I beg to differ. There's a lot of sexual and sometimes disgusting stuff in Surrealism - after all, sexuality is an important part of the unconcious. Just take a look at some of Max Ernst's drawings and collages. this one, for example - it's actually pretty harmless compared to some others I couldn't find on the internet. Here's another one.. but again: harmless compared to others.

EDIT: also check out Hans Bellmer's illustrations for "Histoire de l’Oeil"

But at least I feel some distance to your examples, Peter. And this is not because they are 90 years old artworks, or greyscale. They do not need explicit material, no high resolution vaginjas and johnsons to make the audience feel uncomfortable.

A main feature of surrealism is that it comes in a subtle way and disturbs your thoughts. And a surreal artworks need not to look like one. One of the mistakes of artists who want to make surreal artworks is that they want to make surreal artworks. The same with Dada.

Maybe I'm too strict about this. I just don't like artworks which want to be surreal, and those explicit ones. And those which are both.
