Hijacked

My ebay account was hijacked this week!

Last night I was looking trough some accounts and websites and came across my ebay acct. It said I had 5 items for sale, a bunch of baseball cards (I don't own baseball cards, especially unopened boxes of them). Then I looked at my acct balance and it said I owed $450...

I changed as much as I could, I cancelled the sales and contacted ebay. It scared me and now I know about internet fraud.
