Here's the situation now: Recently I had a new-user (chill061) who, over a 2 day period, had bid and won 8 or 10 items from different sellers and not paid for any of them. I was the third seller to send "chill061" an NPB alert, and eventually "chill061" had his account suspended, but all of those sellers lost money (listing fees, final-value-fees if they didn't collect), but ebay still made money (from the listing fees) and of course "chill061" had a good time and didn't lose anything.
I wish ebay would collect a $20 "new-user fee" from new members, which could be passed on to the sellers as re-imbursement for the listing fees, and would offset some of the risk of selling to a new user. You could still have non-paying bidders but at least you wouldn't actually lose any money from new-users like "chill061".
What do you think, Did I miss something?
