Have you posted any?
Maybe you've got great taste in games and have Resogun on PS4. Maybe you've downloaded the update and uploaded a ship. Maybe you leave a comment below. Maybe people read it, download it and you have eternal adulation from people who recognise you in the street as that guy/gal who made that awesome user-created ship in Resogun. Sure, it's unlikely, but if you don't try, you'll never know.
