There's an allure to the faceless artist on the web, and in real life. It's the same idea as the faceless motorcyclist in black. They can be anyone, maybe someone beautiful. Your dream lover.
When art is made, and there's no face to the artist, you'll conjure up a pretty face depending on the art. With "dark art", or whatever you call that crap, you'll picture a sleek edgy guy who enjoys Poe and wears black all the time. If there's any hints of femininity, you'll picture some girl in torn black clothes with funky colored hair.
Tim Burton wannabes are usually pictured as post high school girls/guys who are stuck in their goth phase and act like that bullshit quirky shit people think is cute.
Art that looks like conventional comic art, or whatever is popular now, are pictured as beta comic geeks. The level of fat and beta depends on how the people are drawn.
There was this guy I used to crush on whose art reminded me of comic guys who have a massive hard on for that Dark Tower series Stephen King did. I think there's a comic series for that? I don't know. The guy I knew would talk about that fucking series whenever he opened his mouth. I think he started illustrating stephen king crap I haven't talking to him in over a year.
We project what we want with the artist who does your favorite art. Sometimes you'll message them and hope they're hot and start a 'star crossed internet lover' bullshit that every tumblr bitch masturbates to.
All in all it all depends on what you like, and how old and lonely you are.
