Ebay Thief

Someone listed golf clubs on Ebay using my account, obviously without my authorization. The scary thing was, they were able to keep on adding listings even after I changed my password. I tried to remove them as soon as I saw them added, but eventually some poor sucker bit before I could respond in time. I pity the fool. There goes his US$180.

What I wanna ask is: What the fuck is up with Ebay's lax security? According to Gmail, my password is rated "strong".
