The way its implemented doesn't check for the referance domain yet; it can be done, yes its easy to do, and no i don't have time to do it now, nor did I have time to do it when I was implementing it. Its on the to do list though.
Just need to write a small check for the first part of the domain matching forum.dead or
http://www.dead.
Idea came from pleasuredome101.com btw, but it saves having to hxxp links.
