There is an entire forum (used to be called Fakebusters but is called something else now) dedicated to identifying unscrupulous practices in the Civil War ebay categories and some members here are active on it. That seller is one of many they have railed about for years and nothing has changed. Occasionally that crew gets something removed, but it's like digging a hole in sand.
There are several others who get away with questionable practices time and again (a cartridge seller has been discussed under the bullet thread and I referred to 2 in response to another thread of yours). We are not the ebay police here and that fakebusters forum went private because some ebay sellers threatened them so I'd prefer not to follow them down the drain and turn this into that kind of website.
Anyone who thinks ebay is going to self police this is delusional. I have reported several fakes in the past week and they are all still up on ebay. The sad shame is getting burned discourages new collectors we want coming into this hobby and is a big turn off that sends them away instead.
So, if ebay isn't going to do anything, "caveat emptor" specifically applies to each of us as buyers to get educated about stuff and who these sellers are. We here can help you although, again, you cannot blame people for unwillingness to declare someone a shyster on a public forum. Still, a lot of feedback has been provided about items within this forum and through private messages and emails. Don't be afraid to ask questions -- this is our hobby so we like to talk about it and do so freely for fun.
