as well as a count for the number of disputes showing for both buyers and sellers.

The problem is that there is no way to judge who is in fault.  Sellers that sell items attractive to teenagers will be opening heaps of disputes for non payment, and will also be targeted by the little scammers claiming INR or SNAD (hoping to get refund or partial refund).  Some buyers can have a bad luck of striking bad sellers.  Some buyers are just too naive and continue to bid on things that are just too good a deal to be true, and never learn their lesson.  But sometimes it is just matter of bad luck; I do not have too many problems, but every now and then I get several within very short time.  Just because somebody is lodging disputes means absolutely nothing; especially as sometimes scammer may claim INR and the seller just refunds because they know that if they cannot prove postage they would lose anyway, so there would not be a dispute showing.  BUT nobody knows if the person is a scammer or if it is their postie or somebody in the street who is stealing their parcels.
