Oh, thanks.  I didn't realize.

Yes, it is.  The program goes through the referer log and compares
those links to the ones it already has, and attempts to retrieve
links from the Web one by one.  Based on whether the retrieval
succeeds and whether the page actually contains a backlink, the
referers are moved among the five categories of confidence.

True.  But even when i run the script periodically, it takes a
long time to do processing.  I *wish* people didn't all use broken
browsers!  If only we could trust the browser not to lie about
referers all the time, all that work would be unnecessary.
