You cannot simply block a seller the way that a seller can block a bidder or buyer, but you can exclude the seller's items from appearing in a specific search.
From your search results, go to the Advanced Search page to the seller section, select "only show items from" and then check "exclude". Enter up to ten seller usernames separated by commas and hit "search". Then bookmark or save the search results. Be sure to use the seller's username as shown on the Feedback page, not the store name shown in the listing if the seller has a store.
If you use the bookmarked or saved search results as the basis for further searches, you can continue to exclude those sellers' items from your results.
