Wasn't there an adult section?

[LUST]

I think I subscribed to a few 18+ wallpapers and they were in adult categories (mostly nudity) but now they are gone and I can't see the adult category as well. Can it be found on non steam app or was it removed?

In the app you can still allow adult content by going to the Workshop tab, clicking on "Filter results" and then by selecting only "Mature" in for the "Age rating" filter. In some cases, wallpapers may be against Steam's workshop rules and thus may be deleted by Steam staff.
