I've already seen similar.
I think this is a scam some companies use to get people to change their password.
Most now push for a stronger password & insist it be alphanumeric.
I also changed my ebay password just in case but I'm still suspicious that the above is the real reason & no one actually hacked ebay.
It is a good idea to change passwords from time to time.
On the other hand I've never had one of mine used by someone else on a web site.
How about the rest of the members here.
Have you ever had a password stolen from a web site & then used ?
