Why did I get a TOS violation?

Hi

I have made several pictures with a specific prompt without any words linked to nsfw content. I was able to post one picture but not another one.. even tho they are made for the same prompt.

This is the post that was accepted: https://civitai.com/posts/893206

And the picture below is the one who did get the TOS violation...

Why?

Otherwise, thanks for a great website :)
