Need a simple way to block Seller from searches

[posti]

Why doesn't eBay set up a simple way to block Sellers?  Yes, you can go through every search and manually enter specific seller names in the search engine, but that is quite time consuming and annoying.  Why block sellers?  Because I get pages of listings for unrelated items where many sellers use blocks of unrelated keywords.  Reporting these violations of listing practices is useless - I have yet to see eBay take action against any of them.  I blocked four sellers this morning in a search and cut the list down by 158 listings!  None of which actually related to what I was looking for.
