I starred out the url but I can tell you I was never registered at po*p.com nor would I want to even know what a forum at that address was about. When you go to the url, its a landing page with ads so I imagine this is a Spam to try to awake some curiousity. They probably get their email list from forum posters elsewhere figuring they would know what this email means. Pretty funny stuff The subject line is "We were hacked"
