Here is an amazing story about a hi-jacked eBay account. http://www.auctionbytes.com/cab/abn/y10/m03/i29/s01
What is amazing is how fast the person's log-in information was used and how many fake postings were made in this short period of time.
While I warn of this in classes, it seemed that everyone is aware of it, so I have been tempted to skip the details. Apparently, it can not be said enough times.
Don't respond to e-mails requesting private information by clicking directly on a link provided by the sender. In this case, I am sure it looked like a very legitimate notice from eBay.
Don't let you guard down folks.
