The seller may block a bidder or potential bidder from bidding on their items if they have the bidder’s user name. There is a Block Bidder link under Edit Listing on the Item Listing. This link is populated with the current high bidder. You can also access your Blocked Bidder page from the Tools for Sellers page:
- Click Tools for Sellers.
- Scroll down to Manage the Auction.
- Click Block Problem Bidders.
Blocking a bidder only prevents future bids; it does not remove any current bids the bidder has on the item.
