How do you propose eBay do that? You already get the FVF back (a minimal payment to the seller?) Given that buyers don't have to have ANY financial stake in eBay. Take it from their autonomous, arms-length subsidiary Paypal account. If they have one.

Unworkable and unnecessary. Just go through the NPB report, leave a strike, block them and move on.

I can imagine how this place would end up if it got a reputation for charging buyers, warranted or not.

As I said in your other thread
