Advanced search options should have a dialogue box for words that buyers want EXCLUDED from search results, just like ebay has. And Blackball should work both ways: buyers should be able to EXCLUDE selected sellers' items from search results. Example: I just now joined ebid to buy an electric motor. Search yielded over 600 hits, but over 500 of those hits were from the same seller, hvacsurplussales, who had "zero" sales, likely because all his prices were higher than retail. Ebid not providing buyers with any means to EXCLUDE words or sellers from searches forces us to go back to ebay, where the searching is much easier, faster and efficient.
