If you were ever stuck into Deviantart long enough ago; DA muro was the tool of many great works of art and simultaneously half arsed wank constantly spat out by pseudo artists to garner attention.
I could even say the same for audio submissions on this site.
No doubt great music and dialogue will be recorded, but a lot of hack bullshit will follow too.
It's the nature of that freedom, I don't see it necessary or helpful to micromanage or ruthlessly police it.
Great art will always swim in a sea of mediocrity, and genuine work will always shine in a pile of cheap, half arsed trash.
I don't consider photography to be inherently creative, sometimes it is; but often it is not. Photography is easily one of the easiest avenues for unartistic, mass-produced, attention seeking garbage... But photography as a pursuit and technique is still valid.
I've been around enough to have been on Elfwood, and those standards were too strictly and subjectively enforced, it was frustrating and oppressive. They had rules forbidding uploading drawings being done on lined paper for example.
I believe it's better for an art site to start out with the very fundamental, morally indisputable rules first... Then modify in measured, well though out response as new issues arise.
