I don't know if you did something, but none of the extensions you posted lead to any real images. They all return back with "Wallpaper Not Found." You're going to have to give more context.
However, if it happens that the wallpapers you posted contained images of exposed female genitals with spread legs, then likely one of the following occurred:
A) The wallpapers you posted as examples had already been reported, and have subsequently been deleted. If they haven't been deleted yet, they will be. There's a massive backlog of reports the mods have to go through on a daily basis and it takes time.
B) The wallpapers you posted as examples do break the rules, and have just not been reported yet. The mods do not go through every wallpaper as it is uploaded; they rely almost entirely on the reports submitted by users to know when there's a problem. Sometimes a wallpaper that violates the rules slips through the cracks, and other times they're caught almost immediately.
C) The wallpapers you posted as examples do not actually break the rules for some reason. Now, since the page codes you posted are broken and I can't actually see them, I have no way of guessing what they were. But I do know that the rules prohibit images of naked women spreading their legs and exposing the vulva, or spreading the labia, or of excessive bodily fluids such as lubricant or semen. However, photos of women spreading their legs while wearing panties, swimsuits, strips of cloth, small furry animals, or etcetera are permitted. So if your photo featured a spread vulva and the ones you listed are covered in some fashion, that would be one example of why one would be deleted over the others.
Again, I can't see any of your examples since the links don't work, but that's my most likely guess.
