Ebay doesn't want to focus on negatives, that's bad business practice, so I doubt a list of bad sellers will ever be generated for public consumption. They do police vendors, but they are restricted by law as to what they can do. It is unfortunate that there are some who will knowingly misrepresent a product for the sake of making money, but we all know how old that story line is. Sadly it will always boil down to buyer beware. On a brighter note, I have been buying things, for years from ebay with only a few real problems. I learned quickly that the seller must be reliable. I've bought many succulent plants never been burned, when I started with figs, that's when I got torched, but only from one seller.
