I just where curious, Usersjs does have Everyone and Friends. But why is tehre no None option or Nobody. You cannot hide right now if you want.
I see option to show myself to Visible to: everyone, friends, no one
Which means you can be seen by everyone, friends or no one.
Show me: has everyone and friends.
Which means you can see everyone or only friends.
I mixed both, tiny font you see. So i possible missed in some way the 'No one"
