Don't you think ebay should have a/c freezing facility for more safety? This facility is available for demat a/c s. You can freeze a demat a/c when you do not intend to trade for a considerable period. This ensures that your shares are lying safely in your a/c and you dont need to check your ac regularly. Also, passwords should automatically change every 14 days so that you cant login if you dont know the old pwd.
Ebay should have these security measures as sensitive info such as cc and ac no are stored on it.
