Block bidders or buyers from your listings.
To add people to your blocked list:
- Go to the Blocked bidder list page.
- Enter the user ID(s) you want to block, and then click Submit.
To remove someone from your blocked list, delete the user ID and click Submit. Let them know so they can start bidding on or buying your items.
P.S. Best way to manage that is to add shortcut to your ebay page.
