I still don't understand that line of reasoning.  How is it that "we
can be damn sure that they're not spam"?  Whether or not a link is
spam is dependent on where it is linked from and for what reason.  You
can't point to any domain name and say that a link to it isn't going
to be spam, and certainly not when you're pointing to a page with
content that can be changed by anyone at any time for any reason.
