I'm convinced it's a tie between Craigslist and Ebay as to which is the larger resource for fences.
No telling what percent of the goods are stolen.
I started a thread a while ago, "where do stolen bikes go", and the responses were, Craigslist, parted out and Ebayed, and traded for drugs. Although I've never know drug dealers to use bikes much, so I'm betting if a bike does get traded for drugs it is quickly sold on Ebay or Craig's.
