why do you want to block them?? if you are saying because they are a "forwarding service" for buyers well I have shipped to quite a few and find them to be good - it gives buyer who do not live in the U.S. to have items sent to a U.S. address from sellers who only ship to a U.S. address
and......you as a seller are only responsible for items once they reach that "forwarding service" - and if they are broken or lost after that it is not on you to replace or refund
