eBay did this same thing to me a couple of years ago but only a couple of hours after the hijacker had sold a laptop computer for about $1000 on a Buy-It-Now. They (eBay) did not tell the buyer of the laptop that my account was hijacked. The buyer wired the hijacker the money.
Why they did not tell the buyer, I'll never know.
The guy lost over a grand and wanted me to refund him his money.
Oh ya, took a week before eBay contacted me with the info and let me back on eBay. After that, I changed all my passwords to a combination of letters and digits that have no meaning. They are the hardest passwords for these scumbags to break, after a couple of tries, they'll just leave it alone and go find an easier target.
