While I was asleep.

So, I changed my password and figured that was the end of it. I did notice they sent a "changed password email" to me with the password I changed it to. I don't recall another company ever doing such a thing, but whatever.
Today, while I was out, one of my deactivated ads was reactivated.

Changed my password again, but this time immediately deleted the email.
Anyone ever experience this? Do you think it's an Armslist or email issue?
