I've not posted anything but WIPs or simple model renders in months because I'm sick of being slandered. I make, on the average, 1 fully modelled and textured house interior w/ furniture a week or so, along with other diversionary fun models for sheer enjoyment. There just isn't any sense in posting any finished renders when all I'm going to get out of it is a couple generic 'oh, ah.' comments and reams of abusive email spam sent to me about it.

I'm not saying I'm any master or anything, but I think 'retarded kindergarten refrigerator art" and the like are a bit overboard. That's a mild example that won't get me into trouble for posting obscene language. I have tons of them on file (I keep them to get a kick out of re-reading them from time to time.)

I used to give away a lot of Bryce freebie models too (furniture, houses, fantasy & sci-fi environments, construction sets, etc.) at DAZ website.
The same attitudes made me just go ahead and delete all of the archives from my site and not bother offering any freebies anymore.

So, I'd say elitism, snobbery, and outright hostility are at least partially responsible for less image posting; at least in my case, which is all I can speak for.

I continue to make models and renders, because that is how I make a substantial part of my living; but I won't post the pictures here anymore. I just maintain a small personal fantasy/sci-fi gallery.
