Except potentially all those photos will be crap and then you'll end up with a really mediocre photo selling website and business will scarred for life.
But you can validate and curate the uploads. In fact, that can be part of your community/crowd-source model, too. If someone else within your community comes along and rates/tags/categorizes the photograph, he can make a little slice of the pie.

I had considered this option, but it doesn't really fit with my current plan which is to focus on a specific niche which requires a certain level of quality.
I will be targeting flickr users though as there are some great guys on there, publishing awesome work just for the fun of it.
