People who don’t pay

Is there any way of blocking people who have history of non payments from bidding on my items?
I’m fed up of things selling and people not paying, sold something recently then sent a payment reminder. When I checked the persons page someone has left feedback saying the buyer didn’t pay 😤 opened a unpaid case but can’t see anything happening because it never does 🙄

Yes there is. I have just blocked two buyers who haven't paid.  Go into your summary page, scroll down to bottom RHC and click on unpaid. On the next page enter the buyers ID.
