I find this funny, only because I go on dA a little more on average than FH's forum and I don't see any web camera porn.
I see artistic photographs of naked women and men, paintings and drawings of the same type and etc, but not what you're describing. Regardless, nudity requires a warning. You might have to change your settings?
I have a very broad term of art. If it's beautiful or if it means something it's art. So, technically, a naked woman posing in front of a camera would be art to me, as long as the photos aren't grainy, or obviously worthless. On the same topic, some "porn" can be considered art because it is still photography, drawing, writing, filming, etc. It still requires effort and the creator still takes at least some meaning in it, or a sense of emotion. (Under that definition, though, I guess murder could be an art >.>')
Oh well. Don't go on dA if you don't like it.
