I do not work for Ebay and I have my own criticisms of them from time to time, but to be fair they are just a private company that is trying to keep things under control enough that they do not get shut down by lawsuits, not only in the U.S. but in other countries as well. They have millions of auctions going on every month and I think that it is understandable that they have to have policies that may seem a bit less than highly refined for each and every possible auction that goes on.
By the way, there is a world of difference between
Hermann Goering and Adolf Galland. Goering was one of the top leaders of the Nazi party and anything related to him from any time in his life rings all kinds of bells in terms of his years as a top Nazi leader to 95% of the people who go on Ebay. Adolf Galland was a pilot who was known as being a less than enthusiastic Nazi including the time when he openly criticized Goering and was sent back to flight status. I had the pleasure of meeting him and listening to him back in 1985.
It was not me, but apparently someone sent a complaint to Ebay about your auction. As the guy told you, if you or anyone submits a complaint about an auction, Ebay reviews the complaint and the auction and if they agree it violates their standing policies they take it down. I believe this is not just individuals but that there are groups of Ebay watchers out there who spend a fair amount of time doing just that. My guess is the groups are likely the ones who got Ebay to include a ban on items they find objectionable - whether it is Nazi, KKK, anti-abortion, unauthorized trademarked items, drugs, sexual services, or whatever. Frankly I'm surprised the list of "banned" or "restricted" items is not ten times longer than it currently is given that there is hardly anything in the world that someone doesn't like.
I think the easiest thing to do is to sell your non-Ebay-able things elsewhere and forget about starting a personal obsession about finding a way around them. Why not sell your Sanke cards here for example?
