I wish there was a way to block retail sellers from clogging up search results! If I wanted items from them, I could buy from their website or physical store. When I'm trying to buy from individuals, I have to plod through thousands of listings from a large in-trade seller. I tried blacklist but their listing still show in my search results. Boo.

trying to block a particular business from my search results and article link above returns 403 error. Can a particular seller be blocked? Thank you
