at this point it appears that even if Bethesda yanks a mod from the site, the files themselves remain on your console unless you choose to delete them - so you can keep deleted mods forever. You'd best download those you find now, because its a good bet even these stealthy ones will get swatted down eventually. If you see something with an odd name like Cool3!~ you can bet you're on the right track. Head to the Work In Progress folder here at Bethesda's Fallout 4 mods page and search through them manually for anything with no photo gallery and no description. but if you know where to look, they absolutely do exist - and are even found directly on Bethesda's website. Posting up something obviously called a "nude mod" in the Clothing or Texture category is a surefire way to get it taken down immediately. Here's the thing: you can't search for these ones through the mod list directly.
Yep, they exist, and yep, you can download them. The Real Deal: Nude Xbox One Fallout 4 Mods
