The copying of a title listing is easily done and not really a breach of policy. If you simply click on your listing and then choose ( sell one like this) ebay does it for you. Plenty have copied mine and I don't really care although I can understand your frustration and annoyance with it. I dont think its fair.

If sellers are taking pictures etc that's a whole different conversation and there have been plenty of previous threads on how this may be breach of copyright. I'm not really sure how that works to provide an informed comment but I am sure plenty of others have an opinion ( correct or incorrect).
