Interesting, I’ve only been here a few days and I’ve definitely seen all three types.
I share both my name and photo because I’m an artist so my info is already public and traceable through my art. If I didn’t share art I would probably keep my name private though.
There are artists that share their art in category 1. @katharsisdrill is one for example.
Oh I’m sure there are! There are plenty of artists that use a pseudonym everywhere. Technically mine isn’t the name I go by on a resume, but it is my real name. :) Everyone has their own way of deciding what’s comfortable for them. :)
