I'm glad you've changed your password - a similar thing happened with me when I suddenly had DJ equipment added to my listings. It was a nightmare as I reported it to eBay, they suspended my account and I had to answer about 10 security questions so they could verify it was my account. It took ages.
I can only think they have a way of hacking the account, as I use various unique passwords (mixture of upper and lower case letters, numbers, symbols etc.) and not even my wife knows them!
