too many books

I should preface this by explaining I love books. However, there is some eBay dealer that about once a week, with a different eBay moniker lists about 1000 books that have nothing to do with corkscrews–yet their listings show up in the corkscrew search. And, each time he/she does, I add their name to the "exclude dealer" list. But, the following week, a new ebay id, and they show up again!

Is there any way we can put a restraining order, cease and desist order, or something to stop ultibuch_de, aha-buch, rheinberg-buch !
