real.
if you want a serious answer though...
Most artists especially once they get serious are aware that posting their stuff anywhere except on an authority account that they own will gurantee that they don't get any credit for it if it goes viral (not that anything from here is going viral kek), so... I kind of don't blame them.
People are also suspicious of posting their serious work in a place that might make others not take it seriously. A board like this is doomed for the /trash/ almost so have to just accept it.
Would be nice to get some outside artists who don't give a fuck about that and watch them take over /art/ though.
