I agree that non-payers should be looked at more stringently by eBay, however negs for buyers didn't work in the past and wouldn't work now - in the past all that happened was that the buyer would immediately leave a retaliatory neg for the seller (or get a friend to do it) , which now with the defect system in place would leave the seller in a no-win situation and the possibility of being deregistered/restricted from selling.
