so listen: all my games with adult content including #Roommates, #CursedLands and #LoveBites (and lol, this last one DOESN'T even have sexual content!!) have been REMOVED from Steam search.
Unless you know the exact URL, you won't even find them searching... not even by NAME! 
eh no clue! but see my latest tweet. Maybe they're just preparing the road to implement that content filtering. But if by default games tagged with adult content are filtered out... not good for exposure
