One of the main problems with commissioning post-vore disposal is the fact that it's vore related.
I also think it's an interesting study about what makes this little community tick. While I *am* complaining here, that's not the only point of the journal. With post vore disposal and macro scat (Particularly when all three are combined) there is pretty much no market at all. But this particular combination of kinks is different from something like diaperfurs, latex, or gore: in those cases you have a fairly public, if small, market of people drawing the stuff. 'Duh, commissioning extreme kink art is hard,' is the reaction I expect. It's hard to commission post-vore disposal and macro scat. First: shout-out to those artists who are down to draw these far-past-the-point-of-insanity fetishes once in a while.
