I dont think you should go after the seller, in any way.

I fully respect that, sadly that is the only method.

I only choose sellers with extremely high reputation, but not 100%( I.e. 95-99) , because :
1) they would care about their rep, and refund me
2) they have done many deals, so the loss won't affect them as much
3) if it's 100%, it indicates they have done very little deals.
