What happens to Non Paying Bidders?

I have just filed another NPB on a non paying bidder and when I checked the feedback of this one I see that he has at least three false positives where he has obviously not paid other sellers.


 


I think that it used to be three strikes and suspension for non paying bidders but another seller told me recently that he thinks that has changed.


 


Does anyone know if there is a definite policy for NPBs ie if you reach a certain amount of strikes you get suspended?
