Hacked?

I just got a thread update email from you guys and it says the message posted was:

The link for the post is: http://www.blackhatworld.com/blackhat-seo/white-hat-seo/337686-how-can-i-find-out-my-accurate-site-ranking-new-post.html (post by MrKennedy), but his post is completely different, and it has not been edited, so it wasn't him...

Any ideas what the problem is?

Ha no idea why he posted that then, and then changed it to something more suitable.

Thanks
