Cause i just get this when i clicked on the link
You said that the host resolved, all i get is a not found screen etc.
But there was definately a webpage here before because this is different from the normal default screen that shows up when you can't find a webpage. But now it had disappeared.
Could they have found out that you posted it on your forum ? hmm ... probably not, couldn't find out that fast or change it that fast.
This is weird
